The apartment is a really lovely space, and well equipped, and it’s only about 15 minutes walk from the main train station. Incredibly comfy bed, and brilliant shower.
There was some food in the fridge and cupboards which we were invited to make use of, which was a welcoming touch.
The immediate area has a few bars and restaurants, and a handy supermarket a couple of doors down. A lovely place to stay in Zürich!
