    Read some helpful reviews of CubeSmart Self Storage, shared by real renters with genuine experiences and honest opinions.

    Stephanie is amazing!!! She is so kind, welcoming and thorough. She made me feel like no bother. Helped me with my stroller, answered all my questions. Showed me multiple different units. Then when my baby started crying she made sure to quickly get through the paperwork and got us right to our unit with keys! She made sure we were confident and had all the information we needed. She has the office as well as the parking lot spotless. She was even outside sweeping in the insane heat when we pulled up. The second we got out she greeted us and rushed to the door to help us out. I highly recommend this place. She also gave us the first 3 months 50% off. Temperature controlled as well! Thank you Stephanie! ... Read more

    I had such a great experience at CubeSmart! ! ended up coming in around 5:58 PM, right before closing, and Ms. Stephanie at the front desk was beyond helpful. Even though it was almost time to lock the doors, she still took her time with me and made sure I was taken care of. She showed me three different storage units, was extremely professional, kind, and honest throughout the whole process. She really helped me figure out the best option for the amount of space I needed, and I never felt rushed at all. If you decide to come here, highly recommend asking for Ms. Stephanie. She's dedicated, knowledgeable, and truly cares about helping customers find exactly what they need. Thank you again to her for making this such an easy and positive experience! ... Read more

    My experience acquiring a storage space was great and pleasant. The clerk was very helpful and patient. Although I did (not get a discount) as a Retired Military Vet. I did get great service. Senior Vets are on limited income. We need all help possible from all sources having made the ultimate sacrifices of our own families.To defend and protect our home states and country as a whole. Saying thank you for your service is never enough for the great losses of our families and many new devoted friends (that had your back with their life). US Army (Ret.) Sgt Renee Bayard-Maatz ...

    My review is based off of the Market Street., Wilmington, DE location. I contacted the leasing office (from the advice of Cube Smart customer service line), to inquire on why I was being charged two different rates for the same size storage on the 3rd floor. I spoke with Noel, who place me on hold (for less than a second) to inform me that it's because I rented them at different times. So, I asked if she can provide the same rate for both of them and she replied, her manager stated no. I asked if I can speak to the manager and Noel than stated the manager just left the office. I told Noel, she does not have to lie. She hung up and would not answer the phone again. This past weekend I moved out of both of my storage units. As, I was moving so we're others with complaints about Noel, the storage rates as well as the rodents/quality of the facility. Both of my units had so many rat fece (lucky I wore gloves). I have most of my items in vaccum seal bags (thank God). However, this Noel person decided to walk around with a cleaning cart (just to be nosey). I noticed so much filth that needed attention which she did not clean. I'm currently renting from the Cube Smart in Newcastle, DE Stephanie (the leasing manager), is amazing, customer service 100%, facility 100% (no elevators). I only needed to rent one storage. The photos attached are pics of filth Noel walked past with her cleaning cart as I was finally leaving out of the Wilmington, DE location. Also, I walked right past a flatten rodent, I'm afraid of rodents dead or alive, so I did not take pic, I ran away. ... Read more

    I had an excellent experience at CubeSmart, specifically at the 4008 North Dupont Highway location (Store #4242), thanks to Stephanie, the General Manager. She was incredibly helpful and went above and beyond to make sure everything was handled properly during my transition to a larger unit. On the exact day I needed to move my belongings in, she assisted me with switching units seamlessly. Despite experiencing internet issues at the time, she remained calm, professional, and extremely efficient while troubleshooting and ensuring my transfer was completed without delay. Stephanie also went the extra mile to clear ice in front of the original unit to ensure safety, which truly shows her level of care and dedication. It’s very clear that she often manages the store independently and does an exceptional job juggling multiple responsibilities—even without having every resource readily available. She is pleasant, accommodating, and genuinely wonderful to work with. CubeSmart truly has a gem in Stephanie at the 4008 North Dupont Highway location. She is a tremendous asset to the company, and I highly recommend working with her. ... Read more

    Stephanie (GM) was excellent. Helpful, pleasant, smiled the entire time. Great prices. Clean. Easy access. Leaving my first review up but editing it. I have come to my unit 5 days this week. The first being the day after it snowed. The parking lot was half plowed. Parking spots not plowed. Sideways barely shoveled. I had to shovel myself in order to get into the building. Three days in a row no one has been in the office so that I could get a cart to get my stuff into my unit. Called customer service and they tried to reach the GM and DM. No one answered do I sit and wait with my belongings. The unit is climate controlled but the building is 37 degrees inside. I would switch storage facilities but what a hassle and a waste of money. Since I have already paid for a month. Finally able to get access to a cart but then I was told I had to get it done quickly because the person had to go back to another facility. They were only there to show a new customer a unit. I guess when they have your money. The customer doesn't matter anymore. Sad times when customer service is only about what benefits the company not the consumer. ... Read more

    My experience hasn't been a good one. I reserved on the 24th online for the 26th. They charge me from the 24th stealing 2 days every month. My 10×10 started at $130 Jan, May went up $155, this month went up to $188.00 , $58 increase within 8 months. Price gouging.. No notice of increase ... Read more

    I am glad to be finally moved out of this storage facility. Half the time the doors wouldn't work, so you would have to drive to another one to gain access to the building and then walk further to your unit. Want a cart on the weekends? Good luck. If no one is in the office, there will no carts because they lock them up. Even weekdays sometimes you won't find a cart. Customer service here was terrible most of the time, but the guy that helped me when I moved out was super polite and cool. Even when I tried calling customer service to make a complaint, they told me the store manager would call me, but they never did. I've rented storage from a lot of different places over the years, first time with Cube Smart, will definitely be my last. Also, prepare die your stuff to be covered by mouse/rat poop. My stuff was only there (in climate controlled building), from July 2024 to April 2025. So much mouse/rat poop, and half the time in the warmer months, it's actually hotter inside than outside. The temperature controlled building is definitely not. Now when I moved my stuff out last weekend, it was pleasant inside, but its only April. Your stuff will get hot in there in the summer. Last thing, don't expect to use the restrooms while there. 9 times out fo 10, they were locked. So I had to pee in an empty jug in my unit. Yeah, not proud of that , but when nature calls......so make sure you go to the Dunkin next door to pee before you spend extended time at the storage facility. So glad to be out of Delaware. ...

    I am so happy that I made the effort to check the New Castle Delaware location out and connect with Anastasia. Her attention to detail and kindness about how she handled everything as well as being able to see that she gets to know her clients was very welcoming. I signed up with the unit and very happy that I did and I look forward to a possibility of transferring all of my storage units from another facility to this one. If all goes well I will be part of the cube smart family and I can also refer new customers to this location. Please tell Anastasia thank you very much for her help. She's a keeper!

    DO NOT KEEP YOUR THINGS HERE!!! My Father passed, so I stored his work tools here. There were a lot of tools because he owned a construction company. I signed up for the promotion of 1 free month then $425.00 right after per month. After a few months the price went to $505.00. If you pay online it's an extra $10.00 a month. It started off fine minus the price increase but then I noticed it was warm but I didn't pay it any mind. On the few occasions I went to meet buyers I also notice a few black boxes around. I thought they were just preventive maintenance. I decided to move everything out and sell some items while doing so it was really hot. The movers noticed this as well. I decided to help the movers so I grabbed a dolly but when I did a freshly dead mouse fell. As the unit continued to be emptied more dead mice skeletons started to be seen. Thank God it was just tools and no furniture or anything made with fabric. This place is not temperature controlled and there are MICE!!! BE AWARE! ... Read more

    I spent 8 months here I had to relocate to another unit due to them jacking up rates but I have to say this place isn’t worth the money. It went down hill fast from the time it opened. Normally everything is locked up carts to help with moving and the bathrooms. Now it’s a complete mess nothing is clean or kept up with. The employees are never around and last night she wouldn’t even check the unit to give me the all clear. This is sad it was a nice place the gate to exit doesn’t work and trash all out back of the building. ... Read more
