The apartment of Christine and Beat was perfect for my week-long stay. It is situated in a very nice neighborhood of Zurich, and conveniently located close to both the main train station and to several trams. The place itself is modern and spacious, features a fully-equipped kitchen, a comfortable bed, and everything else that one needs for a pleasant short-term stay.
Beat and Christine were very friendly and provided an excellent introduction to the apartment, and even left me with comprehensive tips for what to do in the city and where to do my shopping.
I can recommend this apartment in a heartbeat, and would not hesitate to stay there again.
