I would rate the hotel a 3.5. We enjoyed the suite with whirlpool. It had a mini kitchen with microwave and coffeemaker, a separate sitting room, and closed-off bedroom. It had pretty nice remodeling. It had 3 TVs- including one in the bathroom. The whirlpool was nice, and next to a large mirror. The shower was large and even had 2 seats.
The breakfast was reasonable. Good place for kids as it has a pool area. We also enjoyed the exercise room. The negatives were that the heater turning on/off throughout the first night kept us up. Even leaving the blower at a constant High or Low didn't keep it from shutting on/off. We just shut it off and that was better. We tried to get a room facing Green Mill for quiet, as it was fairly noisy all night with the road traffic; however, all suite rooms face the road.
It was convenient to be near the Green Mill, and we ate there twice. The Marine Art Museum was a great site to see. Overall, a recommended place for Winona visit.
