The worst motel I’ve ever been to ! There was ROACHES in the room , the floor in the hotel room would leave your feet Black from how dirty the floor was . The towels they provided had stains on them! AND to top it all off there was a group of men sitting by the stairs drinking beer and making me and my girlfriends uncomfortable! They were there BOTH days of my stay . This motel people also live in it

The first room we got was off. The a/c didn’t work and a couple of items were outdated. However the person at the front counter gave us another room and turned out perfect. Great location, clean and all the amenities you need. Great room, location and customer service.
