The room was tiny and cozy, but unfortunately the stay was uncomfortable due to a few issues.
There is no air conditioning, and during our stay in mid-August the room became unbearably hot at night. A fan was provided, and we had to open the window for air, but the noise from passing cars (even at 3 a.m), made it nearly impossible to sleep the first night. Even with all the windows closed, we could still clearly hear loud car noises from the street.
Another inconvenience was the lack of a refrigerator, so any food or drinks had to be consumed right away.
On the positive side, the location is excellent, directly in front of the tram and train stations, across from the Zurich National Museum, and with a supermarket just across the street.
Overall, while the location is great, the combination of the tiny room, heat, and noise made the stay unpleasant during summer season.
