Sevi's place worked out really well for me. It was within easy walking distance of Zurich main station, which was really important. Communication and check-in were smooth and clear - absolutely no issues at all. The apartment was exactly as Sevi describes. As he is very clear about, the apartment is in a nightlife area. I stayed on a Friday night, which meant that the area was in full swing. I've spent most of my life in big cities, so it didn't really bother me much and I slept without any problems. Sevi is welcoming and friendly and even gave me some good ideas to explore the area. If you're not bothered by the nightlife (as I wasn't), then I definitely recommend this place.
