I and my partner had a really good time at their house. Luiz and Martin and their lovely cat Sian were best hosts!
The house is located on the hill, so you can see the beautiful mountain view from the balcony.
Also I enjoyed the night view on the way back from the central.
It's easy access from the main train station, quiet residential area.
We enjoyed cooking and drinking at home, it was really fun to talk with them as well.
I'd like to stay with them when I visit Zurich again in the future:-)
