We just stayed one night - the owners collected us from the train station which was helpful with a lot of luggage and a wheelchair. Owners are very friendly and helpful.
The room was large and comfortable for us 3 adults, with an elevator for easy accessibility. As the room was on the top floor there were skylights with windows and blinds that could be electronically opened. There were plenty of other windows, with a great view to the mountains, but you need to bend a little to see through them due to the sloping ceiling. A few extra pillows for sleeping would have been nice, perhaps we could have asked though.
Food was lovely in the restaurant, perhaps a bit expensive but I think that's typical of Switzerland. A beautifully decorated hotel and it's a shame we couldn't stay a few more days.
