The pool room was warm, well stocked with towels, plenty of chairs and the water in the pool was comfortable to swim in. We stayed in February during a bitterly cold weekend and the pool room was like being outside on a warm summer day. The staff was outstanding. It will be our place to stay to help combat the extreme Buffalo winters.
