Check in was easy but a bit difficult to find the room. Room was very out dated and everything inside besides the bathroom was old. The lock to the door never worked either. Breakfast was good. Probably wouldn’t stay here again unless it was the cheapest option again. All other hotels in the area are overpriced

Breakfast and the pizza was very good. Staff in the restaurant were really nice and friendly. The bottom sheet didn’t fit at all making the bedding not very comfortable.
