Communication with Christine was great: quick responses, all queries covered. Christine is very friendly and helpful, taking care of her guests.
The house itself is old and may need some refurbishent but Christine mentioned it was in agenda and some works were scheduled. If you do not like carpets on the floor, ask and book downstairs room.
Contrary to some other reviews, I did not find the house dark. Maybe the kitchen was a bit dim but the rooms (in the sunny weather of course) are bright. The balcon room I had was brighhter than in the picture.
It is a convenient and cost effective place to stay if you move in to Zurich and need a temporary place until you find some permanent flat to rent (which may take time). It is a good district where I felt safe and I loved the proximity to the lake and the center from where you can commute easily to your work in your first days/months.
I would also recommend it for tourists because of its great location.
My stay was nice, also because I had luck of having friendly and respectful neighbors.
(you still have to share the bathroom and the kitchen with the occupants of 3 other rooms, but I was never a problem even we all were working).
