Very quiet, pool was clean, room was clean…could have had a microwave in the room for extra convenience but that wasn’t a deal breaker….only downside was price, for motel setting was a little high for my taste ($171) for one night….

The hotel is spotless. I would have given it a 5 star except the check in was not informative or friendly. After the check in I didn’t see another person at the front desk until I checked out 4 days later.
