The flat is located in an extremely calm area, where now, in Spring, the only thing you can hear are the birds singing. The place is charming and cozy, and the room itself is wide, confortable and very bright, to the point that I had to do sort of an effort to leave the place instead of staying home to sleep. Moreover, by walking you have access to multiple public transports that will take you more or less anywhere in Zurich.
In the other hand, Jung Soo is very, very friendly and hospitable. Conversation with her was fluid and nice, while she even gave me some very welcomed tips about the city. So, for sure, it's been a pleasure to meet her.
In conclusion, yes, I will try to stay at Jung Soo's the next time I go to Zurich. :)
