We enjoyed our stay at Niels' place in Zurich. It was exactly as described, with great light and lovely views of a fairly quiet city street. Check-in was a breeze and we were surprised to find a lovely basket of snacks and coffee for our stay. The internet access was wonderful and speedy. We would certainly rent this flat again if we are ever in Zurich.
Our only criticism is that the bathroom is a bit old and has an awkward layout. That being said, it was perfectly acceptable for our needs.
