We had a fantastic stay at the ParkHotel in Zug - a superb junior suite room, very friendly & helpful staff, and the luxury of a heated indoor pool & sauna. Our five year old daughter was well looked after and treated like a princess by the hotel employees. Breakfast was included over the weekend and a truly outstanding buffet to cover all tastes, with cooked eggs & bacon, fresh croissants, a wide selection of meats & traditional Swiss fare - all the way to mini donuts and cakes.
The hotel is a 5mn walk from the old town of Zug where you can enjoy reastaurants and the lakeshore - we didn't try the hotel's own restaurant but they had live piano music creating a very nice ambience.
At night it is totally quiet, we kept our room windows open as we like to allow the fresh air to come through, but there was not a car nor airplane to be heard, nor loud revellers, which is a rare luxury these days!
Overall very highly recommended and we'd love to stay again.
