We enjoyed our stay at Hotel Euler. The location is a bit outside of town near the train station, but there were trams right outside the hotel which took us downtown to the Christmas markets. The room was clean and comfortable. We didn't have breakfast at the hotel since it wasn't free, so we went to the Starbucks next door. The hotel looks like an old elegant hotel and although it shows it's age, they had some nice touches such as a piano player in the evening.
