Josch is an excellent host and his place is a GREAT location for exploring Zürich and the surrounding area. It can comfortably fit 3 people, but is also great for solo travelers. If you read his detailed description, there won't be any surprises. The building is next to the S-Bahn tracks but I slept just fine. 4 tram lines and 2 S-Bahn lines are within a 5-minute walk. You can be to Zürich Hbf or Altstadt in less than 10 minutes. Can't recommend this place enough, especially at its price.
