Great little apartment with everything we needed. 10 minute walk from the train station and 10 minutes to walk to the lake. It had a small kitchen with a fridge and hob. Free tea and coffee was also provided.

"The hotel is conveniently located to transport options. It is an older building but ok. The breakfast is rather average compared to most places and overpriced, but it is Switzerland and everything is overpriced."
