Awesome storage facility just outside of the city. The spaces are clean, dry , and secure. I can drive inside the building to do all of my loading which is great when it rains or in the winter. The customer service is 2nd to none!!

I've been a customer for over 10 years and have upgraded my storage unit twice over that time. Staff is knowledgeable and always proactive on the logistics of moving and storing. I would recommend Castle to anyone needing a convenient, safe and easy-to-navigate storage facility.

Highly recommend Castle storage facility! We were moving out of Boston and had to store our belongings before the movers came to ship them overseas. We ran out of space in one storage unit and had to get a second one - the managers were super nice and got us a second unit close by the first, as well as not charging us full month price for it. They were super helpful and flexible when we needed to organise a delivery to the storage too! Definitely recommend, very good customer service!

Amy was super helpful, explained options and helped get me set up in no time at all. The best option in South Boston for storage.

The storage its self is very clean and accessible. Right off the hallway and between two train stations. I would recommend anyone in the South Boston, Dorchester, South End and Downtown Boston area.The staff at the storage were very professional and are there to help you all the way.

I have been renting from here foe a while now and I'm very impressed with h service and satisfaction of the facility staff. Never had a problem so far they always give me heads up if there is a concern or changes in the facility...I recommend them to whoever would like to choose a good and well respected storage facility.

You can get inside with your code, and the motion sensors turn on the lights as you wander around inside looking for your locker. Spaces to pull up/back in your truck, too.

I needed a small storage space and Castle offered me a unit that was absolutely perfect for what I needed. Jean Paul was very friendly and helpful, in fact when he showed me the unit I did not believe that my belongings would fit in what appeared to be such a small space, but he reassured me that it would work and he made it happen.

Castle storage provided a simple and easily accessible place to keep our treasures while downsizing until we could find a home for them. Scott, the manager, was friendly and helpful upon arriving and departing Castle Storage.
