Room was exactly as described, small but comfortable. The bar below was really fun, great vibe and some beautiful Swiss music and the locals were fun to chat too as well. We never met Katie, but the 72 year old lady who ran the place was delightful, very friendly and helpful.
Just be aware the check in does take a long time as they require your passports and make you fill in forms in German, we had left our passports at the train station in a locker and we tried to give a photocopy of our passport to our host, but she requested the original passport of all guests otherwise you can’t stay here. We have never experienced that before with an Air BnB place. So make sure you have your passport with you if you want to stay here!
