Sevi's place is conveniently placed near the train station, has everything you need, and Sevi is a great host. I found him easy to communicate with and willing to accommodate most requests made in due time. The apartment is in one of Zürich's more happening streets, I didn't find the noise terribly disturbing, but really light sleepers might. If you are not a super-light sleeper, the rooms are cheap for being in the middle of Zürich, clean, and I would easily stay there again and recommend it to others.
