“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!.”
“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..”
“JPL was excellent explaining the details and processing my payment. He was extremely helpful and efficient. MPM.”

“Super clean and great management. I've had many storage units around the country and this place was perfect for what my daughter needed, a short term....”

“I rented a small storage space at Castle Storage for 18 months and it was the best self-storage experience I've had. The location is easily accessible.....”

“We just finished one year of renting at Castle in South Boston and had a very good experience. Our unit was clean, free of pests and smells, and nicely....”
