Staff was friendly. Pool was warm and seemed well kept but the state of the hotel was not good. Wallpaper falling off walls, giant chunks missing from walls, desperate need of paint throughout the building and the room smelled bad once we got to it.

Clean and spacious!

We had a king accessible room which was large and comfy. The bathroom was clean and spotless. There was a decent variety of food for breakfast, and the dining area was spacious. We would definitely stay here again.
