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

    I’ve used a lot of different storage companies in my life and dealt with a lot of people on various storage sites. There’s a young man who works at the St. Paul Avenue location in Milwaukee who puts them all to shame and his name is Kobe (with a name like that how can you not be a legend). Can’t say enough good things about him. Make the man mayor and the city shall rise. ... Read more
    Mathieu E. - 25 October 2025
    I don’t usually leave reviews, but I had to make an exception after the incredible experience I had with Extra Space Storage — all thanks to Kobe. From the moment I walked in, he was friendly, professional, and genuinely eager to help. He took the time to explain all my options clearly, answered every question with patience, and made the entire process completely stress-free. The facility itself is clean, secure, and well-maintained, but what really sets this place apart is the customer service. He went above and beyond to make sure I was comfortable and had everything I needed. If you’re looking for storage and want top-notch service, ask for Kobe. He’s the real deal! Thanks again! ...

    I had an exceptional experience with an employee by the name of Heather. She was very knowledgeable, helpful and made the best impression for me as a customer. Great customer service I would absolutely recommend others to come here. Be sure to stop by and say hey to Heather! ... Read more
    Tevin H. - 12 June 2025
    They should change the manager, Heather gives horrible treatment, I came for a storage unit and practically slammed the door where their name cards are. After opening my storage unit, she got in with some guys who seemed to be her acquaintances because they came in laughing, she attended to me at 5:02 pm and she's supposed to go up, open the storage units, and come back quickly, it's 5:40 pm and she still hasn't come down. There's a couple waiting the same amount of time as me and they haven't come down yet, people like that shouldn't work dealing with customers, if you prefer to lose customers, keep giving her work because she'll scare everyone away, check your cameras and keep an eye on everyone, or well, I don't know if it was just me because of my physical appearance (race). Thank you very much, I hope you take the comments into account to improve. ... Read more
    Jomira Q. - 15 May 2025
    SUCH A PAIN IN MY LIFE!!!!!!!!!!! HEATHER you are the worst manager I ever encountered. this lady has caused me so such stress I really want to hire a lawyer for pain and suffering. First of all I have been renting with this exact same storage space for the past 4 years with 0 problems all until Ms Heather has been managing the property. They give you a decent rate at first and then months down the line they raise your rate without a warning. My rate went from $106 to $150 in almost 3 months without my acknowledgment I was almost behind 3 months with a $120 foreclosure fee. I've asked to speak with a supervisor she gave them the wrong number and I was contacted but could not be reached. My balance was up almost $500 then I proceed to pay off my storage balance and without notice & my consent my lock was cut off my storage unit and it was replaced with there own personal lock without my consent I have movers that I have to post pone due to my lock being removed and they are the only ones with access to my storage as of now WOW, I was scheduled to move as of Sunday when I asked the store (MOE) because Ms Heather does malicious things and does not want to show face he told me which I can hear her speaking to him in the background that they can leave my storage unlocked and unattended due to my lock being cut and that would be my only option. there is no telling if I have valuable's missing or if my storage was rummaged through iam currently living in another state how will I ever know ? Please be aware of this Storage space this is absurd and iam very pissed off. Iam yet to speak to a supervisor and I have been trying to reach him/her for the past 8 months! This lady needs a reality check you do not own any storage spaces you do not determine any move out date nor when and how anyone pays for there unit. Nobody and I mean NOBODY told you to remove my lock this lady makes decisions without customers acknowledgment I have NEVER dealt with anything like this in my life. You can contact me and let me know my things would be auctioned off but you can acknowledge me and warn me your about to cut off my lock and my balance is PAID IN FULL? WHERE IS HER SUPERVISOR???????? ... Read more

    The customer service at this location is really nice and very helpful. I believe her name is Heather, she showed me how to access my unit, use my app, and appropriately use my lock which I really appreciate it. The space was clean and easy accessible. By using the app made my first time experience smooth and easy. ... Read more
    Taquanda G. - 20 April 2025
    I’m pretty sure I was discriminated against. The owner SETH also owns the property across the lot from this storage place. He told me the unit was ready & available over the phone & during the showing. The very next day when I submitted my application his verbiage changed to “I have a few applications on this unit”. It’s been a week and a half with no follow up about my application being approved or denied. Was it even processed??? I guess I wasn’t the white, I mean right tenant for him since he’s actively advertising the unit without notifying his current applicant of their status. Very unprofessional, would not recommend ...

    I’ve had a storage space here for almost a year and have always had a good experience. The customer service is friendly and helpful, and there is always someone at the desk during business hours. I use my storage unit for work so it’s very important to have consistent access and support. It’s also a great location right off the freeway, so I plan to keep using this facility for the foreseeable future. ... 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.

    5x5 or 5x10 units are great for smaller loads, such as chairs, lamps, small furniture pieces, boxes, books, and documents.

    10x10 or 10x15 units work well for larger furniture, bicycles, appliances, and the contents of a small apartment.

    10x20 or 10x30 units can typically fit the contents of a three-bedroom home, including large furniture and multiple appliances.

    If you’re unsure which size is best, a unit size calculator can help estimate the right fit based on the items you’re planning to store – helping you avoid paying for more space than you need.

    Climate-controlled storage units maintain consistent temperature and humidity levels, helping protect items from damage caused by heat, cold, or excess moisture.

    You may want climate control if you’re storing items that can be sensitive to temperature changes, such as furniture, clothing, appliances, paperwork, photographs, artwork, electronics, or wood and leather goods. These units are especially useful for long-term storage or in areas with hot summers, cold winters, or high humidity.

    If you’re storing durable items like tools or outdoor gear, a standard unit may be sufficient. When in doubt, climate control offers added protection and peace of mind.

    The facility at 420 West St. Paul Avenue is accessible during regular access hours, typically Mon-Fri: 9:30 a.m. - 6 p.m., Sat: 9 a.m. - 5:30 p.m. Office hours and gate access times may differ, so it’s a good idea to check the facility’s posted schedule before your visit.

    To open your storage unit door, start by unlocking it, whether it uses a traditional padlock or a Bluetooth-enabled smart lock. Once unlocked, grab the bottom handle and lift or pull up the roll-up door until it’s fully open.
