Nice place! Disadvantage, 2 separate buildings. Restaurant, bar, pool, and hot tub had no indoor access, they were across the parking lot. Otherwise was clean and staff was friendly.

  • Disliked: Cleanliness, staff & service, amenities, property conditions & facilities

The room was so dated and dirty. While you could say the charm is that it was a hotel that clearly had a hay day in 1980, it would go a long way to keep up with maintenance and cleaning. The jacuzzi tub didnt work, lights in the bathroom just stopped working randomly, the bed was on wooden slats (no frame), the heater was coming off the wall, the smoke detector was hanging from the ceiling, etc...
