We stayed in Zurich for 5 days. We found the studio spacious. Sebastian was always willing to make our stay better and more comfortable. His response to our queries were also very polite and timely.
Description on the AirBnB page contains most of the information, which is quite handy as well. Overall, it was a nice experience and we would surely stay at Sebastian's place the next time we visit Zurich.
Thanks for your efforts!
