    The facility is clean and easy to access. Allison is amazing at answering all questions and giving a tour/orientation for new user sign up. I’ve used several storage facilities, this so far is the easiest access and comfort for moving and Allison is a top notch h professional in this space. ... Read more

    Alison & Jade are fantastic and really supported me through the process of getting into my unit. The issue wasn't their fault but I wasn't left alone for a second. This team is great and I highly recommend the facility. ... Read more

    Chelle - 4 March 2026
    This will be my go to storage building as long as I’m in Denver. Booking the unit was very easy & smooth. Store members are always on sight & ready to help no need to wait for anyone. Not only that Allison has always been very helpful. There were times where I couldn’t come up with the payment & she always tried to work with me as much as she could. Not only that but she understood my situation & didn’t treat me as a client but as a person. The whole facility made me feel welcome & comfortable. So much that I’m actually on my way over there to book another storage unit. (Also because I’m not comfortable staying where I’m at so I’m leaving that place lol ) . ps Allison is very beautiful she should let me buy her a drink ?? ... Read more

    Cindi K. - 28 February 2026
    What an unexpectedly great experience… Well, I was in need of a last minute storage unit near cap hill and I knew about this place from when I lived near it before. I’ve never actually used a storage space before but I gotta say, from the call to their headquarters, to dealing with all of the staff here (Allison, Ethan, Omar) everyone was beyond my expectations of kind, courteous, genuine, and professional. I will absolutely use them again in the future and appreciate everyone for taking care of me. Oh also, it was only $30 for this unit for the first month, so definitely a great value ... Read more

    Rosa P. - 1 February 2026
    Allison and Astro are amazing! Update: My unit was broken into a couple of weeks ago but the staff didn't know since the thieves didn't actually break the glass doors to get in. Allison has been very helpful in the process of filing police reports and working with the police to figure out who the thieves were that broke in. Thank you all for great customer service and providing a clean location for storage. Out of the 3 years that I've been here, outside of the recent robbery, we've never had any issues with any uncleanliness and any issues are fixed immediately. Bonus points: They have a big parking lot. Of course there can be a price hike, but in Downtown Denver it is expected. I am sure the city is constantly raising the price of the building's property tax, same with renting an apartment. Added photos of break in. If you haven't checked on your unit in a while, be sure to do so soon! ... Read more

    I was renting at Public Storage on Fox street and made several complaints about a rodent problem. So in my search I went to the ESS location on Grant Street and Evette and Allison talked me through their policies and showed me the facility. They were very helpful and knowledgeable ! 10/10 service ... Read more

    I can’t recommend this Extra Space enough - Alison is AMAZING and endlessly helpful. She made a stressful time that much easier, and made sure I had the storage size that was right for me. She was also readily available and responsive. Get your storage unit here! Thanks Alison! ... Read more

    I had the pleasure of visiting an extra space storage with my boyfriend last week. When he came into the office today I was pleasantly surprised on how fast the process was. We had some other things to take care of today so the fast, quick, easy lease was exactly what we needed. Thanks to Allison and Zendae for helping us with this. 10/10 best experience I’ve had with a storage company. ... Read more

    Allison went above and beyond for me when I moved my things into storage a month ago. She actually stayed an hour past closing so that I could come set up the unit after work because of the pickle I was in. THANK YOU ALLISON!! You really saved the day and greeted me with wonderful energy and a smile. 10/10 would recommend Extra Space Denver. ... Read more

    Joshua B. - 26 March 2025
    Facility is nice but after 3 months they doubled my rent. Went from $74/month to $158/month with less than 3 weeks notice Edit: I did call and they did lower it. To $105/month. That’s still a 35% increase after 3 months. At this rate I will be paying a mortgage to you in a couple years. I also want to point out that no value was added to me with this price increase. No additions to building, no extra services, no anything to justify the price hike other than business want so business take. Genuinely shameful business practice. I also want to be extremely clear that all employees I have spoken with have been extremely nice and helpful, it’s just unfortunate that they have to represent a business like this. One star is too many ... Read more

    This is literally the best storage unit place in the entire city! This team is absolutely incredible… They will work with you, they will take care of you, even if you are in crisis, they will be understanding and help provide you with support and love. Please please please make sure you come here and see Francisco and Alison and Jessica and I promise you you will feel like you are family. I would not say it if I didn’t experience it myself and see it happening with multiple people in this building. We are building a community over here! Lots of love to you, can’t wait to see you over here on Grant Street!! ????? ... Read more
    Rachel T. - 28 December 2024
    This place used to treat me really well under the old brand. Today I noticed they had quietly increased my rates 50% (!!!!!) over the last year or so. There must have been at least 3 separate increases this year alone when I started to go back and look. (They say they mailed the notifications but I never saw em and everything else is done by email so obviously the tactic is to slip it by unnoticed.) If it were a reasonable increase I wouldn't care. But quietly raising them every few months to a total of 50% is some real chef's kiss corporate behavior. I fell prey to the oldest trick in the self-storage book. Shame on us both, I guess. Edit: I did just call you. That's how I cancelled. I'm not sure what you want to discuss. If you'd like to refund me the entire amount above what I agreed to when I signed up, please go right ahead and do that. You have all my contact information so by all means utilize it if you feel a burning desire. ... Read more
    Thomas R. - 24 December 2024
    I am updating my review. I’ve been a very happy customer for 2 years! I am so happy a family member (also a customer) told me about this storage facility. I now have two units here, and also have a friend who has a unit here. The place is very clean and secure. I feel safe dropping things off at night. The units are temperature controlled, plentiful carts, TWO parking lots with dedicated parking on both sides of the building, THREE large elevators, and sliding door entry ways that stay open long enough for you to situate your cart. It’s also very clean. After hours access is very handy. The prices are really competitive. The management is AMAZING. They will get to know you and are personable. They understand what you store is important to you. I’m very happy. ... 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.

    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.

    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.

    If you’re using the unit for the first time, make sure the lock is properly removed before opening the door to avoid damage.

    Security helps protect your belongings while they’re in storage and gives you peace of mind between visits. Many self storage facilities use a combination of features such as video surveillance, gated access, on-site management, and well-lit premises to help deter unauthorized access.
