My parents stayed at Chris' place for 5 nights and were pretty disappointed of the service provided. Even though the flat is well located, it was not clean (there was a lot of dust around the bed / night table and the kitchen ustensils were not properly washed) and its overall condition was truly different than what the pictures described on the advertisement. On top of that, the walls are very thin and the neighbors very noisy, which did not help my parents to enjoy a calm stay at Chris' place. To conclude, I would not recommend this flat if you are looking for a quiet place to stay in Zürich ! For younger people, I guess that would be ok..
