Close and clean facility with decent prices.

Good people at a good location. The lady we dealt with was kind enough to give us a move in special. Big savings that were greatly appreciated.

Very friendly, caring people, clean and quite facility.

Had my stuff in storage there for over a year. I never had an issue getting ahold of someone to pay my bill or with any questions. I moved from a large unit to a smaller unit, just a phone call and I was moving my stuff the next day. They were always very nice and understanding. I miss that place!

Leigh at Cheswold is great to work with

We used Sentinel at Cheswold for 6 months in between 2 houses. Leigh and the staff are very pleasant to work with and very accommodating. We were there Sept 25 - March 15. No problems with bugs or odors. Got a call one day ASAP when we didn’t put our lock on correctly. At the time, the price there was the lowest in the area.

Recommended: Yes
