We were hoping for a nice experience as the location is beautiful.
However, there were 3 major problem. 1) The house is immediately next to a high speed train line and even with all windows closed, the noise was many times a loud roar all day (every 2-10 minutes) and all night (every 10-30 minutes it seemed). Some Swiss trains going by are quiet, but many are quite loud, especially the freight trains at night. We did not sleep through the night because of this. This listing should be removed from AirBNB.
2) The hosts also did not disclose this is not a freestanding house. Their own house is built attached to this property like a row home, so they are next to you the whole stay. The photos provided by the host hide this fact.
3) Upon checkout, after putting our luggage in the car, we found the husband and wife screaming at each other in the house, and then they screamed at us about not returning both keys (the wife was in fact holding both keys in her hands which we had properly left in the house). We had also broken a soap dish and left them 20 francs extra on top of the cleaning fees and laundry fees, and were shocked 3 days later to receive a $1500 invoice claiming all kinds of other problems we promise we did not do such as a broken mirror which our child supposedly broke who can not even reach the mirror.
In addition, their copy of the repair invoice for a "broken mirror" which was not broken when we left was actually dated before the day before we even left the house. So more possible deception from this host.
They demanded we do an "inventory" of the house with them, but given their hostile behavior and screaming, plus an unpleasant email we received from them the day before checkout, we left as quickly as we could.
We have stayed in many AirBNB's with good hosts, good properties and had excellent experiences. We recommend staying away from this one as we had one of the worst imaginable AirBNB experiences here. Perhaps living next to a loud train may have affected the hosts as much as it affected us during our stay there.
