When we arrived around 5:30, the front office was already closed and we were lucky to run into and employee who took us to our room. The room was very run down, but clean enough. No bed bugs. There were a lot of flies however, which I thought was odd. Traditional style lock and key and in a super cute part of town. It’s right down the street from base so that’s really nice. Overall it was ok.

Parking is convenient and safe. the room was clean and the shower worked well. I didn't find any utensils in the kitchen, but I didn't need any. The refigerator was running but the stuff I put in there wasn't cold in the morning. In fact it was barely cool. But I slept well.

This motel appears to also be home to low income housing. I feared for my safety so I DID NOT end up spending the night. There was an overwhelming odor of bleach upon entering the room. There was no safety chain or dead bolt. Blinds were broken in such a way to give straight line view to the bed. That person on the 2nd floor watched me in my car for 30 minutes
