The hotel is in the “red light” district as such, but this was no issue for us at all. There are a number of nice and reasonably priced (for Zürich) eateries nearby, particularly Asian cuisine. It is close to the train station and close to the city centre, easily walkable.
The staff on reception were always lovely and the hotel room was simple but nice, if a bit warm. My only issue is that the beds aren’t the most comfortable, but not so bad that it can’t be put up with for a few days.
