Very central location in Zurich. Perfect walking distance to anything; the river, the train station, grocery stores, and the lake.
The apartment was very clean. During the summer it can get pretty stuffy inside, but the hosts provide a fan. Other's have complained about how loud it is, but with the fan on we didn't notice any outside noise.
The internet speed is very fast, 80mb down. Having access to the laundry in the basement was very helpful, Pablo left very detailed instructions on how to use it.
The only downside, was if you wanted to keep the window open the smell of cigarette smoke would fill the room.
