Nice value for the apartment. While not huge, our group squeezed 4 people into the apartment (2 on a bed, 2 on a pullout couch) and made it work just fine.
The apartment was very clean and had necessary amenities, including a small built-in kitchen unit.
Location was tremendous, right in the heart of where you'd want to be as a visitor to Zurich. Getting to the train station was easy (10 minute walk) and there were many restaurants/bars/shops within a few block radius. Also a grocery store about five minutes down the way, which was a nice way to get a break from the high prices of food in Zurich.
Chris was on time to check us in, responsive to questions we had, and friendly.
I'd recommend this unit as a good place for a somewhat budget minded traveler.
