This was a really great stay for my extremely short trip to Zürich! The location is it's best feature. Checking in/out was a breeze. I think this was my first stay not having any communication with the host until I'm already gone but it wasn't a problem as the trip details had everything I needed. There was quite a bit of noise outside but I simply shut the window and was completely fine the rest of the night.
A couple things to note; the apartment is on the first floor which is accessed by walking up stairs. I was not aware of this and if I had large bags, it would have been an issue. It didn't seem like there was an elevator so it's not handicap accessible either to my knowledge.
Smaller things include the towels appearing to be used based on how they were displayed, no hand soap in the bathroom, and no trash can in there as well (if I were sharing the space with someone, that would be a bigger issue). I've communicated these to the host and she responded promptly, so hopefully the next guess will see the improvements. Also, the comforter on the bed was quite short and didn't cover the whole thing...this might just be a personal preference of mine though.
