My friends and I had a great stay at Niels's place. We didn't meet him or his friend Luis but communication and instructions for entry were perfect. They also agreed to a late checkout which was very much appreciated. The apartment is comfortable and fairly spacious with a fully equipped kitchen. Perfect for four sharing (we were a couple and two singles) but you could get more in if people are happy to share the large beds. The sofa could double up as a bed too if you have a sleeping bag. Zurich was quiet because of the public holiday but the area seemed fine and the apartment is a 10 minute walk from the Wiedikon train station which takes you straight to the city centre and/or airport. Be warned though - it's an expensive place!
