    Absolutely amazing experience! Francis was incredible in helping us when we were stuck outside. He was very kind throughout the entire process. We are so grateful for his support and would highly recommend this service to anyone. Please give him the recognition and promotion he deserves—he truly went above and beyond! ... Read more

    My rent has doubled in only 2 years. And with all the extra money they’re making, major things are breaking and not getting fixed. BOTH bay doors are broken right now. The elevator smells like urine ALL THE TIME. The bathrooms are disgusting. These people are greedy and pathetic. ... Read more
    Spira L. - 19 July 2025
    Very professional and clean local storage facility. Support staff friendly and knowledgeable. Easy access to building via digital access on the app. Large freight elevator and hand carts for use. Very happy with my experience using Extra Space Storage ... Read more
    Amy H. - 8 July 2025
    Clean, dry, and temp controlled storage at affordable rates. Convenient location for most parts of central Cambridge/boston. Well secured facility. Drive way may be narrow for large moving trucks, and there is no loading dock. Ramps and carts are available for use. Manager Louis is friendly, professional, and helpful. ... Read more
    Jacob B. - 7 July 2025
    Awesome customer service this afternoon. The latch on my unit has been sticking and I’ve just been putting up with it. Today I went down to the office and within 20 minutes my unit had a whole new latch. Thanks so much. ... Read more
    Kellie A. - 6 June 2025
    This facility is a safety hazard. I got trapped inside because the exit button didn’t work. I was pressing it over and over and nothing happened. I had to frantically call my mother to help get me out. This could’ve turned into a dangerous situation if I didn’t have my phone on me. A storage place should never put someone in that kind of position. Please take safety more seriously. ... Read more
    Tj S. - 8 April 2025
    I highly recommend the Extra Space Storage facility at 51 McGrath Highway, and especially the manager, Luis. My family and I have been storing here for several years and just moved out. We had several extenuating external circumstances that resulted in delays and complications. Luis couldn't have been nicer or more helpful -- he is calm, kind, thoughtful and resourceful. Couldn't ask for better customer service. The previous owners had neglected the facility towards the end of their term. Luis turned that around -- there are no pests, it's climate-controlled and very clean with new carpeting and a large, secluded parking lot. An excellent choice. ... Read more
    Kt K. - 31 March 2025
    I recommend Extra Space Somerville on 51 McGrath Highway as a storage facility. I have stored here for 16+ years and experienced 4 ownerships. The place has come a long way in having a great manager, Luis. He keeps the facility clean and pest free (very important!). He is professional, genuine and does everything he can to find solutions and help customers. Bathrooms are locked but you can ask to use them. They recently put industrial carpeting throughout which is much better than concrete floors. ... Read more

    We've rented here for a year, and our experience has been fantastic. Louise has been incredibly helpful during our move to a larger unit, always communicating clearly and showing so much patience and kindness. The rates are competitive, and the spaces are clean and secure. Highly recommend! ... Read more
