Sandra is a very kind and friendly host. She made lots of notes in the house to explain the things. If sometimes I still encountered some issues, she always helped me out quickly.
The house is not in the center but has very nice connections to HB as well as various districts of Zurich. Plus it is next to the hiking trail to Uetliberg. The room is simple yet cozy and clean.
Overall, it is suitable for solo travellers who enjoy nature and tranquility. And also for cat lovers :)
