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

Dump. From the check-in to check out this place sucks. Had to track down clerk for about 30 min before check in. Room in terrible blue conditions. Smoke detector hanging by string...broken lights. The towel on shower was damp....not sure if it was clean. Advertised continental breakfast.....surprise clerk not in office and it was closed during breakfast. I dont usually leave bad reviews but this one really was asking for it
