Good stay at Chris and Carine's. Carine is very nice and helpful, we did not meet Chris in person. The house is located in a very quiet area, 5 minutes walk to the tram 2 stop (Feldegg strasse). When we went there, tram number 4 was not working because of roadworks, so it was longer to reach the place from the main train station.
The place is clean, Chris and Carine are also living in the house with their daughter but the 2 apartments are well separated and it is possible to have some privacy (bathroom is private, toilets are shared).
I recommend this accomodation!
