    The staff was helpful, explained everything clearly, and the process was quick and so so so stress-free. Jr, one of the kind staff members, made the whole experience so much more easier too. He was patient, helpful, and answered all my questions without making me feel rushed or even silly for asking. The whole place felt clean and secured which made moving everything feel not so overwhelming. Prices were also insanely reasonable for a storage unit in New York. Would definitely recommend ...

    Not very happy to be honest I Set to rent on 21st St. and Broadway in Manhattan but it turns out that somehow the room was rented on 17th St. and 10th Ave., Manhattan well, I was left out in the cold overnight with all my things because of this era once I was able to move in to 21st St. and Broadway after the second month they more than doubled the rent more than doubled. I was paying 107 and it doubled to $230 something dollars. Which I had no choice but then to move to 17th St. and 10th Ave. the hours was better for me and they would give me my discount as well. Well right after moving in less than a month later that I was changed from T 10 PM closing time to 6 PM closing time which did not work for me. so now I am stuck moving my things once again to 21st St. and 10th Ave. this has been very difficult moving from place to place because of the different schedules and the pricing that has been given, I’m hoping that this day at 21st St. and 10th Ave. it doesn’t give me the same issues cause I would hate to have to move again ...

    I had a great experience renting storage at this location (Chelsea). I wasn’t sure of the unit size I needed so I went to see for myself. Garrette helped me out by giving me a tour of a bunch of different units. He was very patient with me, helped answer all my questions, and gave off a genuine vibe. Tony was there on my move in day and he was just as helpful and kind. The location, access, and security of the building is great, but having guys like Garrette and Tony around makes the whole experience even that much better. ... Read more

    Garrett’s was very helpful. I needed to trade units so that mine was in a building with a ramp. He accommodated me. When my lock didn’t work on the door of the new unit, he gave me a lock that did. I was very pleased with Andrew as well, when I first came in, and he arranged everything. ... Read more

    At the 510-520 W. 21st St. facility it is very fortunate to have, over several years contact with him, a great and caring customer service person like Tony. He listens carefully to your needs and shows you units that will address these needs. If there's any maintenence adjustments he tries to fix them in a timely fashion. I've always been very satisfied as a result. Recently I've increased the number of units that I'm renting as well. Very pleased. ... Read more

    I’ve been with Manhattan Mini Storage for 20 years and it’s been a safe, clean and secure facility all that time. Recently I had to rent a slightly larger space and Cyrus the manager was awesome. He showed me several options and then took care of all the paperwork and made it super easy to make the switch. He’s very professional and answered all my questions quickly and honestly. I highly recommend this place on 21st Street! ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.

    5x5 or 5x10 units are great for smaller loads, such as chairs, lamps, small furniture pieces, boxes, books, and documents.
