Amazing place! Beautiful castle, beautiful view, large and cozy room. The kitchen is very well equipped. There are enough pillows, blankets and towels.
If you don’t have a car, you need to schedule your day in advance as the closest train station is very small so trains to/from Montreux Gare only leave once an hour from 4 am to 11 pm. Furthermore, the closest bus station is about 10 minutes away, in a descent street. To go back to the castle from the bus station it takes a little longer as it is a climb.
