I went here to help a friend move out. It's a secure gated facility and coded doors. No bells & whistles & they play music in the halls. I was hearing music & thought it was a toy in a unit & looked up & it was from speakers. Its kinda narrow in the halls & definitely an established building and business. The storage neighbors were all older folks I noticed and no one super sketchy hanging around. So thats a plus.

Staff is very kind and helpful. Brannigan showed me around, answered all my questions, and helped make the rental process streamlined and efficient. Facility is very clean and well kept. Facility feels very safe and secure. Prices are very good in comparison to others in the area and they offer move in specials. Very pleased with my storage needs here.

We signed up online for a storage unit (inside 5x10) as there was a promo being offered. We had to go into the office to complete the paperwork and showed up at 5:30 to find the office locked even though they closed at 6pm. We were able to find an employee after 20 mins of waiting who told us we needed to show up 30 mins before closing to complete the paperwork. Nowhere online did it say that. We had to redo all of our paperwork in the office and later found out we got signed up for a more expensive (heated) unit than we signed up for online.

There was also an admin fee charge that we were not aware of. The assistant manager was very nice though and helpful when explaining the bill and subsequent overcharge we had. The facility is nice and secure and I would store stuff there again if I needed it. I have just learned to look closer at the paperwork and ask more questions.

The staff and management were amazing specifically Yesenia Wihoite. She was able to get us a storage unit (10x20) in a pinch and even provided a free box truck to make moving a lot less stressful! The overall experience was a positive one. Good value and clean/convenient location! Highly recommended!

A great group of people to work with. They run a top notch organization. You get what they promise. They go out of their way to make you satisfied. They take security seriously many cameras and well maintained site. Friendly staff who are eager to find solutions.

I lucked out finding this place, and I am so happy I chose Sherlock rather than one of the larger chains. I can't highlight enough how clean this place is: the grounds, the roads, and the units themselves. And on top of that the office staff is organized and friendly. I changed unit sizes about partway through and they were very accommodating - anywhere else I would have been charged fees upon fees. Would definitely recommend.

I rented a unit for over 1 year at this location and I do not regret my decision! Staff members Yesenia and Brannigan operated on a level above excellent; great customer service. Relative to security, I was not worried at all; top notch security (cameras, security, and location). I would recommend this place to friends and family.
