I lived I Rakhal's appartement for three months. The location is great. Tram/bus stop right outside the door. 15 mins tram to city center, 10 mins bus + 10 mins walk to ETH central campus and 10 mins walk to supermarkets. Nice and quiet walking/running area is also really close, along the river or on the Käferberg hill (with great views).
The appartement has all you need for a stay. One large main room with kitchen and a large bedroom. For people used to quietness, traffic can seem a bit loud some times. But nothing too problematic.
Rakhal was very nice and responsive. I truly enjoyed my stay.
