Michal was away during my stay so I didn't get to meet him, but he was so helpful with all information, directions and prompt communications ahead of my stay. He even checked in with me via email while I was there to make sure all was OK.
The room was perfectly appointed with everything a traveller could need, and the location was really close to central Zurich - 1 stop on the metro train or 10 stops by the tram at the end of the road (Lochergut). There is also supermarkets - Migro and Coop within waking distance.
I definitely recommend Michal's place!
