In order to spend the night and have breakfast in the morning normally. The rooms are very small, in April it was quite cool in the room (on the last day I found an air conditioner there that seemed to be able to warm up the room, but I did not have time to check). The temperature and water pressure are good, the breakfasts are delicious.
For 650€ (5 nights 2 people) not very much (not enough pre-booked).
For the price ±300€ for 5 days to sleep normally.
