- KSKayden Swan3 days ago5.0The entire process of setting up an account and paying was easy.
- JWJoy W W6 days ago5.0OMG, 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

- EJEunah JooFeb 11, 20265.0The 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.
