    My experience was awesome.... Osvaldo. P went out his way for me and greeted me outside as I was waiting to go inside. He gave me a tour and made the whole check in process very smooth.

    I want to say that Donte is a really hard worker and keeps a positive attitude in such a crazy building. This morning I watched a lady curse him out over the door code not working. He apologied and after she was done he said I understand and do you need help carrying that box to the cart. I have been a tenant for 4yrs and this building is at its best right now... ... Read more

    I writing this to shed light on a horrible situation. I'm a tenant at Upper Darby CubeSmart. And I'll be very honest the building has turned around for the better. It's not as many building issues since Donte has been here. It's starting to feel safe again. When Donte is in the building is presence is felt. He's a upbeat guy he makes you smile and laugh, very good demeanor. But his problem is he doesn't have any help. I see him catching all the homeless and kicking them out. It's not time since I've been here. Not seeing Donte walking the building make sure everyone is ok. And checking units for homeless people. Some has gotten very aggressive but Donte is a pretty big guy when voice changes, so does the situation. They all leave but news one pop back up. If the building has someone like Donte at night to keep the people out and another Donte in the morning to keep the building safe. This would be the best storage facility in Delaware County. ...

    Does the gm for upper Darby CubeSmart ever get a break. I see him helping people load there items, chase down the carts for Extra space ????, constantly walking the building asking everyone are they ok or need help. My question is who helps him. With they way that building is with the random homeless people trying to sleep in there. The women arguing in front of the building. He does his best to keep everyone happy. And always has a smile on his face a positive attitude, funny jokes. But no relief. If you had 2 Dontes that building was be amazing.. He deserves some type of award for what he deals with and never breaks down. Have a heart CubeSmart get Donte some help and gift card for what he does ... Read more

    The CubeSmart in upper Darby has a great staff. Donte runs around the building making sure everything works the best way possible. And the new addition Kayla is very helpful with getting a new unit. I see the building moving in the right direction. I've been a tenant since 2022. And I have seen it all but these 2 together are great. ... Read more

    No staff and no power during business hours. Yesterday morning around 10am (9/27) I couldn’t get access to the main entrance because there was no power. After I entered the passcode, the door didn’t open. Then I went to the office seeking help but the office was closed. No staff was working during the business hours (Cubesmart business hours include Saturday 8:30am -5pm. Usually there is staff on site during business hours including Saturday. But yesterday, there was nobody and the entire storage location was shut down -during business hours. And there is no helpful phone number in this type of situation. If you call the 1800 number, you will only be greeted with machine recording on weekends including Saturday business hours. Poor management! Extremely poor service. ... Read more

    I would like to say that the GM Daunte is doing a great job at Upper Darby. He keeps a positive attitude in such a horrible building. No matter what the problem is he does his best to fix it and make people smile through his day. I watch get yelled at by teanats about the broken elevator and he goes and hits a few buttons and then tells the tenants all fix and enjoy your day. And goes on fixing the other issues. I've listened to him talk to the college kids about their future. I wish he was a manager here a long time again I see this building turning around for the best and I'm glad I'm a tenant again. Thank CubeSmart for giving us Daunte. GREAT JOB!!! ... Read more

    Pros: The clerks/ store manger all seemed very pleasant and Mack was really polite and helpful and even apologetic for the issues that I had. Cons: on Sunday 5/31/25 when i attempted to use my newly rented unit to store my belongings there was an office lock on it instead of my move in kit being prepped for me. I had to call customer service and speak to them for about a half hour and at first they told me it was nothing they could do but the they eventually helped me with figuring out the lock pad number to enter my unit. It was frustrating because I was using a U-Haul and was almost out of my rental time for the truck. Once I was granted access I then found out that neither elevator was operating and for 2 days I had to use the stairs to get my items to my unit. I saw several people using the stairs and it was a lot of work having to use the stairs for large and heavy furniture ... Read more

    Brittany the manager is absolutely amazing. She went above and beyond for me, helping me reload carts and move things since I was alone. She was so helpful and understanding. I am so glad I went with this location. I’ve never had such wonderful customer service. Anywhere. That woman needs a raise and a medal lol. ... Read more

    This is the second time I've visited my storage and found someone have been in there and stole some of my things. I have one key in a safe, the other one I have. I never shared my key with anyone but yet things go missing. I reported it the first time to the district manager and filed a claim. They denied it because it wasn't a forced entry. We'll, they had fired an employee who had a key and was going in other customers storage. I lost the first time about $3,000 worth of things. Plus I had boxes that was emptied. I forget what was in the boxes. I go in there today and found more empty boxes, storage in disarray . I had boxes covering a fridge in there, now I can see it! No one in company helps. I was thinking of calling the news. I once had people to move me out of there but during that time the elevator was broke for about a month.I lost that money. So think real hard if you are planning putting your things in this place. I'm really fed up. I pay insurance . It's a waste of money they refused the claim. I'm going to try and put another claim in for the second time. If I'm not reimbursed. About the staff, Brittany and Andrea are the best. They are very professional.. they go out of the way to be helpful..they need more staff staff like they are excellent at their job and go all out to help all customers.. ... Read more

    The unit was falsely advertised as a 22x11, without disclosing the fact that it had an irregular shape (more like a triangle). I calculated the square footage to be around 100 sq ft, more in line with a 10x10. When I called later to try and negotiate a lower rate, I was told the only option was to move to a different unit. Additionally, the floor layout at this location is ridiculous and requires multiple hairpin turns and going down multiple ramps and corridors just to get to the elevator in the back where I could access my unit on the mezzaine. I should also mention the rodent problem which appears to be corroborated by other reviews- I did observe some mouse droppings in my unit as well as a live mouse in the hallway as I was vacating my unit. I have since moved to a newer, cleaner, ExtraSpace facility with a much more accessible, true-to-size unit, and better rates. ... Read more

    I promised Mr. Don and Mrs. Ellie, the agents that helped us set up our CubeSmart account, that I would write a review to voice how terrific helpers they were! We interrupted Mr. Don during his lunch break but he still showed exceptional customer service skills with his willingness to assist us. Mrs. Ellie was just as amazing, during our second visit, to start the service. The facility is well maintained and professionally ran. They both showed us a unit and made it super easy to reserve that unit. They effectively communicated an expected price, reservation date, possible service dates, and Mr. Don also showed flexibility with scheduling to start the service. Mrs. Ellie showed grace to make sure all account information was accurate and reflected new customer discount details as a brand new customer with this location. I hope Mr. Don is enjoying his vacation, wherever that may be. I look forward to a great storage business relationship with this location, especially with Mr. Don and Mrs. Ellie working there! Thank you for your time and assistance! It will always feel great when employees show how great they are and how excited they are to help you! ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.
