For a one night stay, this was a clean, comfortable, non expensive option. The front desk staff was nice, the parking was great, the room was clean, the beds were comfortable, the air conditioning was nice, the shower was alright. Rooms with wooden floors are fantastic. We just needed a clean place to sleep for the night and this is what it was.
