Location! Location! Location! You are staying in the heart of Zürich. Step out of the door and you are where the action is. All of the old town is within a 10 minute walk max. Be aware, however, that this is not a quiet spot opposite a bar and next to a church bell. The soundproof windows, however, do a decent job. The host is also quick to respond. I needed a drying rack for a longer stay, and also wanted the wardrobe doors fixed, both of which was resolved quickly by the host.
The apartment has everything you need, although the furniture is quite worn out, and cleanliness was also slightly below expectations. Also: If you are looking for a romantic place to stay please be aware that there is no decoration whatsoever. This was fine for me, it actually gave me more space for my stuff, but if you need knick-knack or pictures on the wall to make it feel like home you better bring your own.
Overall, would rent again if i come back to Zürich.
