Petra and Hans were excellent hosts. They communicated clearly with me from the time I got in the train in Berlin to the time I left for Zurich. They are incredibly friendly people, and can speak English well. They fed me three times during my stay and the food was excellent! The house is a very short 5 minute walk from the u-bahn station, and the ride downtown took 15-20 minutes. I highly recommend this spot for anyone.
