I was in this accommodation for 6 weeks and had a great stay. The room was really comfortable, clean, light, had everything that you could need. The guys in the flat were super friendly and helpful, yet totally respected personal space. I was welcome to use the kitchen and the common areas, and found sharing a bathroom to be no problem at all. The apartment is in Oerlikon, so may not exactly be close to the centre of the city, however with the bus stop right outside the house and the transport connections being very frequent, you can actually be at Zh HB in just 15-20 mins. Would stay here again if I come back to Zurich :D
