I always felt our possessions were safe and well cared for

We have been with Sentinel Storage for over 2 years and have worked primarily with Debra throughout that time. Because we travel a lot and are Florida residents, communication has been key. Debra always made sure we were aware of any changes in price or other policies during our 2 years there. When we talk to Debra in person she has always been professional and personable. I always felt she had our best interest in mind. I would recommend this facility. I felt safe whenever I was there and always felt out possessions in storage were safe as well.

Fair pricing and clean, friendly

It's a clean storage facility with video monitoring. I'd love to say that pricing was higher then others but it really wasn't it was fair pricing. Everyone I have dealt with at this location in Middletown has been great to work with. When I was calling around some storage facilities got excluded by simply how they spoke on the phone.

To use a military term, Outstanding!!!

Mrs. Martin is, by far, one of the best site managers I have ever delt with. If there is a problem, she addresss the problem immediately with complete satisfaction. She has an excellent business attitude and is very professional. She has always greeted me with a smile. She always walking around the facility to insure all is in accordance with the requirements of the rental contract and the facility is clean. Thank you,

Sentinel Self Storage is absolutely amazing!

I have used lots of storage companies over the years, and you come to expect poor service and trashy/dirty facilities as the norm. Sentinel however is not that at all. From the first moment I walked into the office it was clear that this company takes their business seriously. The office is clean and the customer service was amazing, very clear on what you are paying for and why, plus really great pricing. The grounds of the storage facility were super clean, and the unit itself was spotless. Can’t say enough good things about this company. I hate doing reviews or surveys, but with the experience I had I felt they’ve earned it.
