In brief: Hotel location close to the lake, personnel friendly, room with an amazing view.
I had a room with a view to the lake, and the view really was charming. I opened the mini balcony doors (or windows), settled down and just adored the view...
Personnel including people in reception, restaurant and cleaning were very friendly in an easy, enlightened way.
The breakfast was very good, including perhaps more sliced fruits etc. than on average, but also the usual components.
A small discomfort was that I could not send my picture attachments from my smart phone through the wifi of the hotel. I only managed to send the actual e-mails. This was not a big problem. In the next hotel I managed to send also the attachments.
For those who arrive by train: follow from the main railway station the trolley cables of bus line number 1 to the south-west (that is, to the direction of the lake). There aren't too many (if any) info maps at the station! However, at the hotel you should get a free tourist ticket with which you can travel on the public transport during your stay in the hotel. For example, with bus number 1 you get to the centre in a couple of minutes.
