Katie and the staff at the bar have provided a good service. I reached the accommodation without problems and I found everything I was expecting, including a city map.
The room was comfortable; the bathroom was nice, although pretty small, the inconvenient thing being that it had to be reached passing through another room (not a big deal, however).
The only (minor) problem was that the WiFi connection was a bit unreliable at times.

The location is super central and hence ideal for tourists. I was able to avoid buying bus tickets for the whole stay.

All in all, I spent a very pleasant stay in Zürich!
