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 love this storage facility! Jean Paul at this location is always helpful and kind. The location is easy to access, clean, and well priced.


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....

Scott was excellent -- efficient, knowledgeable, curteous. JP very friendly and welcoming.

Very happy with the service and the location. Customer service is great, they make sure all is in order before you sign the papers. Place is clean, storage rooms are spacious enough. Location is great and very convenient.

JP was very helpful!

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.
