Be prepared if you book in summer as there is no AC/fan and won’t recommend it for a group of more than 5-6 people.

5.0

The property is good overall, however we booked as a group of 8 and it is a bit small for a group of 8. We would have appreciate if we have been told in advance that there are only 6 single beds available.

− The toilet washlet was not working during our whole stay which was a big discomfort for all of us. Also, as it was summer, we really felt the need to have an air conditioner (could have been a portable one as well) or at least a fan. There was not even a fan available at the property.

Winter for ski

8.0

Very cozy place and all you need to feel at home. It's at least 25min fron the nearest ski resort and same for supermarket.

− The location is a bit far from anything else. Also the heating system is not so good during the night as it turns off or make noises.
