    Very clean, reasonably priced, very helpful and pleasant staff! Highly recommend! Appreciated the staff working with me on pricing when my introductory rate expired.

    OMG, customer service was off the charts! Pablo is the consummate professional! Although he is the Manager for several buildings, he was available for little things, which were not so little for me - like how does this lock work or can’t close and lock up HELP! The storage spaces, halls and elevators are extremely clean. I’m giving Xtra Space 26 W Diamond in Gaithersberg five stars.9 ... Read more

    Joe N. - 19 February 2026
    The staffs are friendly, and they respond quickly. They provide needed information clearly and accurately, so communication with them is very smooth and efficient. It seems like they do a great job with warehouse patrols and maintenance. On moving day, they provided clear information so everything could proceed smoothly. After that, I was able to continue renting the storage unit at a reasonable price. The location is also convenient. ... Read more
    Eunah J. - 11 February 2026
    Can’t recommend this place enough!! The staff at this location is fantastic! Pablo has always been so helpful since the day I started storing items here. One day, my dad and I were pushing a heavy dancefloor up a hill to move from one unit to another, and Pablo came to help push! The location is always clean and well maintained and I’ve never had any issues. I’ve been storing here for at least 2 years now and will definitely continue to! ... Read more

    We had a fantastic experience with Pablo, the Manager at the Extra Space Storage on 26 W. Diamond in Gaithersburg, MD. He is truly professional, kind, and provides excellent customer service. Pablo helped us secure two perfect-sized, super clean, well-lit, safe, and easy-to-access storage units. Best of all, he even helped us get better rental rates than any other storage company we researched in the area and continues to do so. We highly recommend Pablo, his team and his facility! ...

    Our firm used the W Diamond Gaithersburg Extra Storage site for several years. We were extremely happy with our experience! Every time we visited our storage facility, we were greeted by friendly, professional service. The building itself facility is clean, dry, well-lit, and secure. Accessing my unit was easy thanks to their convenient hours. I especially appreciate the climate-controlled spaces. They kept our items in perfect condition. We had interactions with Pablo (the manager), Chris, and Jennifer in the last few weeks when we were there clearing out our units. All of them are a credit to the organization. All of them were thoughtful, professional, and considerate. They were always keen on keeping the site secure, and clean. This place truly sets the gold standard. Highly recommend to anyone looking for well-priced storage! ... Read more
    Amanda M. - 31 July 2025
    Pablo and his team at Extra Space Storage (I’ve been with them since they were Life Storage) are absolutely FANTASTIC. Pablo has helped me on more than one occasion with my account, and the sign-up process was made super easy by him and Cedric. It was an emotional time when I started renting a unit, as I was trying to find a place where I could keep my precious and sentimental belongings from my late grandma’s house. From the moment I walked in to their office, they were welcoming and understanding and more than accommodating as we worked out which unit I would take, and the logistics of my move-in that weekend. They also explained everything super well so that I felt comfortable moving forward with the whole process and leaving my things in their care. The building is also very clean—Pablo does a great job managing things overall. Highly recommend!! ... Read more
    Anne J. - 9 June 2025
    The managers, Chris and Pablo were exceptional. They are straight forward and down to earth and very informative. The only gripe I have is the rent increase. It went up over 50 percent after 3 months. I simply had to go to another location which was more affordable and more space. The company itself doesn't seem bad so I just rented at another location with the same company. ... Read more
    Luis L. - 3 June 2025
    My experience with life storage was wonderful and pleasant. Their personal are helpful and friendly. I am thankful to Pablo one of their employees that help me with all my questions about my unit. I would definitely recommend Life Storage in Gaithersburg!!!! ... Read more

    We were really impressed about how helpful and knowledgeable Chris was at the W Diamond location.

Thanks for all your help Chris!!! ... Read more

    When Covid-19 pandemic hit our world, in 2020, we were pressed to rent a storage unit to accommodate most of our offices’ stuff, equipment, and so forth since we were forced to downgrade in a large scale due to the circumstances. After shopping around I decided to rent a unit at Life-Storage, the location on 26 W Diamond Ave in Gaithersburg, MD. The climate controlled units, the easy access to the unit, the level of safety and security that they provide to the facilities, and the maintenance by keeping the bldgs clean & up to date with the necessary tools handy to assist renters when moving in or out of the units have been some of the reasons why I stayed all these years. The courtesy and great customer service provided by Chris, Pablo, added to my peace of mind knowing that I was in the right place and that our belongings were secured in terms of their financial & sentimental value. Now that I’m vacating the unit, I must give Chris a huge thumbs up ???? for making our next step a lot easier and bearable. I only hold gratitude to him for his kindness and outstanding customer service and I wish him and the staff @ Life-Storage well and blessings in the new year to come. If the need for renting a store unit arises again, I do know now where to go and strongly recommend them to anyone reading these reviews looking for extra storage space! (Ms. Gonzalez) ... Read more
