The staff was great and the rooms very clean. The only issue we had, and this was significant, is that we were not informed ahead of time that the hotel was under construction. During one of the days, there was no running water in the rooms from 9:30 AM to 5:00 PM. For me that was ok as I was at the office. My fiancée on the other hand, who stayed at the hotel, could not shower or use the bathroom in the room during that time! That is NOT acceptable! Hotels in Zug are expensive, we payed more than 300 Francs per night for a regular hotel. For that price we expected to at least have been informed of the construction at time of booking so we could make an informed decision, and to have planned accordingly.
