I've stayed in Rosanna's place for almost 2 weeks to work in Zürich, and even if some small attention was here at my arrival, I wouldn't recommend the apartment for more then 2 days...
First of all the bed I really soft (my back hurts every morning).
Second the WIFI doesn't work, when you are here to work, it's a bit too bad, i had to spend 40.- to upgrade my phone GB in order to have Internet.
Third there's no possibilitie to cook, for a AirBnb it's really too bad, when you know what you pay in Zürich to eat, it's 50.- very day at least...!
Not to mention the drunk neiberhood just right next door...
