My experience with Stephanie Kennedy was very professional and helpful. Not only was she personable and highly knowledgeable, she recommended movers for me. I would highly recommend her AND this particular property of Extra Space Storage to anyone. Thank you!

Stefanie was very friendly and helpful. The price was great, my 1st month was free and everything was clean and well maintained. Was nervous abt the neighborhood but she put my concerns to rest.

I worked with Lindsay. She was beyond helpful. She got me in the same day that I called. Rented the storage quickly. She also gave me the online discount since I had made the reservation online. I would recommend them to anyone. Secure gates. Private access. Thank you

Stefanie is a stellar manager with excellent customer service. I arrived with my packed goods and Stefanie was on lunch but quickly made me her priority for the next half hour. Along with showing me my original reserved unit, Stefanie was able to offer me a slightly larger unit with a wider door to make it easier to move my items. After all that, I realized I forgot my lock and Stefanie allowed me to borrow one from the store. All in all, Stefanie made the move in process as nice as it can be (we all know how awful it is), giving us ice cold water and often helping us in and out of the gate. I cannot express enough how fantastic she is as a person and as a professional.

Stephanie is the real MVP. She went out of her way to help me out and was more than helpful in helping me choose a storage unit. Thanks for the great service and keep it up!

Go here! Use their facility. Stephanie and Lindsay are the absolute best. You don't expect to meet genuinely great people when you are going to store your "stuff," but that is what happened. This is an awesome family run business that actually cares about their customers. I came from out of state and needed to store my RV and this was the easiest thing I have ever done. I want to come back to Denver just to see them. You will not be disappointed. THANK YOU!!!!

Stephanie was fabulous! We called in advance in preparation for our big trip to store our truck and our camper and she was extremely helpful. She was very helpful each time we called and check in was very smooth. Very impressed!
