Certainly a central space in Zurich, but not one that's made for the most comfortable of stays. the pictures also portray a slightly larger room than is actually there. You couldn't have the furniture in the different configurations shown in each picture...
It has enough to be able to cook a basic meal and everything was certainly clean. But, the small fridge in the room was particularly loud, forcing me to unplug it every night (not good if there's something in there that has to stay cold). The blinds were also quite poor at keeping out street light glare. earplugs and an eye mask are certainly a must!
I would also not recommend this place for anyone with poor balance. the shower/bath has a very high edge that is very difficult to get out of.
All in all, fine to stay in for a bit if all you want is centrality, but doesn't feel like a space put together with much care...
