Property needs updating. Gym has most of the equipment not working. Room doors don’t seal light from hallway which means noise comes through as well. No bathroom in pool area. Overall price is in line with property. Breakfast was very good. Staff was attentive.

After a long drive and a long drive ahead, booked the rooms for the family here bc it had a 24 hr fitness room. We all had stiff legs and sore backs and needed some exercise since it was also snowing out. However, fitness room was closed, for the last three months due to renovations. Website should have indicated status. Breakfast had options like yogurt, fruit and cereal that were fine but hot items (eggs, sausage) were pretty poor. Stay was not worth the price,
