Read some helpful reviews of Extra Space Storage at 11855 East 40th Avenue, shared by real renters with genuine experiences and honest opinions.

Weird situation happened today. A skinny guy staff open the door while I was getting into my stuffs. Very unfriendly, I ask him is everything ok. He didn't respond, pretending to looking for something and then left. He came in just to look at me. This never happen with other staffs. He is the new guy that I never met before. I thought He was gonna do something to me or looking to steal my stuffs because now he knows what is unit. I will have to move out soon. Very uncomfortable. ... Read more

Staff was nice enough, I had to get a bigger unit at move in and they helped without a fuss. Units were clean and doors weren't broken. My only gripe was that after 4 months their "promotional rate" expires, and they try to increase your monthly rate by almost 50%. I just moved my stuff to a different location rather than pay their increased price. ... Read more

Yan truly is the best employee to have and that you want to do business with, he is beyond understanding and helpful as he listens to you like a conscious kind human who not just makes you feel heard but does his best to actually help you.. this man is why I chose ExtraSpace and the only reason I didn’t go with one cheaper and closer because this is the kind of person I want to work with and for as he needs to be in charge so that the service level/rating of any company he helps run will drastically increase as Yan knows how to help serve customers and is one of the people you meet that restores your faith in humanity! ...

Bell - 15 February 2025
Previously had an account in Indiana. Moved to Denver and received a quote of $45. Since i already had an account they just asked to update my phone and email NOT my address. When my rate went up to $90 i never was informed of this via updated email or phone number i was however apparently sent a letter via mail to an old address in Indiana which was never updated. Was planning a camping trip over the summer and went to my storage unit to grab some things over the weekend. I noticed everything had been disorganized. When i spoke to the office staffed they mentioned someone had broken into several units earlier that week. Again was i never notified of this by either email or phone number until after the fact. I was then moved to an indoor unit which apparently is more secure 2 stars because this location is close to my downtown apartment and half the price of closer units. Only a 10 minute drive away ...

Let me start off with the fact that this is the most unsafe location I have used, and I've rented in several ESS locations around Denver. You can see in other reviews that units have been burglarized. Part of the issue is the area has a lot of homelessness. They rent units here and hang out in their units. I have come here in the evenings many times to find people sitting and even cooking inside units. On occasion you'll drive down one of the rows and see an open door on a unit get closed from the inside. There is a walk through gate that is only supposed to open from the inside, but it doesn't swing closed. The homeless will leave it ajar for their buddies to come in. The road in front will often have people living in their cars as well. The facility is also extremely tight and difficult to maneuver around. I have a Superduty F250 and it's very difficult to get to my unit. Safety is only part of the issue. I'm an over the road trucker who lives in my rig, so I store things I don't need with me. You always have to play the 'switch locations to get the online price' game when they get too high on rent. They play games with the rent. You'll get the the online price and then after 2 or 3 months they'll slowly start raising your rent. After a few raises I just go online and rent at a different location and move. This time, I've only been there 3 months and they've DOUBLED the rent. I was paying $43 a month for a 5X10 unit and got notice that they're raising it $83. I went online to see what they're currently renting for and their web rate for the same unit is $41, less than I'm paying. I also went and drove around the place and they have no less than 18 storage units vacant. I wanted to speak to a regional manager about the rent game and other issues so I called the office and left a message requesting the regional manager contact me. I get a call back from Cliff, who tells me he's the location manager. I ask him how I get in touch with the regional manager and he asked my "what do you need to speak to them for?" I told him that I wanted to speak to them about several things "including the freaking rent going up again." He became indignant, saying "He doesn't handle that I do, and you have to go through me. And you can get as angry and upset as you want but rents go up." He was very belligerent and testy, and I told him I still wanted to speak to the regional. He replied, "Well he's not going to help you, I'm the one who handles it, he's just going to pass it back to me, and if you want me to look into it I will, but I'm not going to let you bother him because he's busy." I said I don't understand why you're being aggressive but I don't appreciate the way you're behaving and I don't want to deal with you, you're being very rude and unprofessional. He then said you're the one being aggressive and saying the "freaking rent." I said freaking isn't a cuss word, I wasn't speaking angrily, I'm from NY and we say freaking all the time. It's not a cuss word. He said "It's a cuss word to me, and I don't care where you're from, I've been around the world twice, and you can call the corporate number if you want." I asked what's the regional managers name and he said "I'm not going to give that to you. You can just call the number on the website." I wasn't going to get anywhere talking to Cliff because she apparently is a very sensitive young lady. I hung up and called the toll free number on the website, but if you already have an account registered with your phone number it will recognize the number and reroute you back to the location office. I had to use one of my business lines to get through to customer service. I let the lady know about my experience and she apologized, saying that is not their policy and Cliffs behavior is unprofessional and not how they treat customers. I agreed with her. She said she would escalate the complaint to upper management, and I requested that I be called back. I will update once I speak to someone at corporate as well as to the regional manager. ...

Got a call 1 hour before they closed. My unit was broken into. When I showed up, he was securing multiple units by putting screws on the doors. The employee working didn't seem to care much. He just said "what do you want to do? Move to another unit?". I asked if a police report was filed. He told no, that's on you... ... Read more

These amenities include Climate-Controlled, Indoor, Drive-Up Access, Onsite Manager, Contactless Renting, Security Camera, Gate, Parking, Credit Cards Accepted, Online Payment and RV Storage.

For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Extra Space Storage - 11855 East 40th Avenue can satisfy all of your storage needs. Different sizes here range from 25 to 400 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
