Although there was a last minute change and I did not stay in the apartment in the pictures, overall I would stay there if I’m again by myself in ZH. As the reviews mention the place is very small, even for 1 person, but the location is unbeatable and it has everything you need for a quick trip. Check in and check out extremely easy.
Only downside is that I never found the containers to leave the trash and I ended up having to carry a trash bag while rolling my suitcase through downtown Zürich. Perhaps they should think of a dedicated space within the premises to leave it at.
