The host was very friendly and easy to communicate with.
Chris warned us that he only had another (basement) room available and we agreed, so no problems there. Sadly, the room was a bit smelly and the kitchen wasn't clean. The WiFi in this basement room also didn't work.
The house is also quite messy. The location is great, but the value was so-so considering the cleanliness, especially since eating out is not cheap in Zurich and no one wants a filthy kitchen (there was a moldy spatula in a drawer, expired food in the fridge, and a bad smell).
