I recently had the privilege of spending three months with Silvia in Zürich, and my stay at "home" ended up being one of the highlights of my trip. It was incredibly comfortable, convenient (extremely close proximity to the bus stop and to grocery stores; modern appliances), extremely affordable (the provided breakfast!), beautiful and spacious, and there were always interesting (and polite!) people from all over the world checking in - there is always pleasant company and good discussion to be found at Silvia's place, and she is keen to provide helpful recommendations about fun activities or important cultural/historical sites. I'm very happy with my choice of AirBnB and am thankful to have enjoyed such a special trip to Switzerland.
