We can not say enough good things about Sandra's place! The location was directly next to a train stop that takes you right to the main station. Her house is a little hidden when you get right off the train stop, but Sandra sent me a kind message explaining exactly how to find her house. She wasn't home when we arrived but she had sweet notes all over the house guiding us to our room and where the bathroom was. Sandra even has a sweet cat named Hanz who slept with us a few nights while we were there. There isn't wifi at the house, but you can pick up a traveler's wifi at the Main Station in the Tourist Center and its not too pricey. Overall we only have positive things to say about our stay with Sandra, we would highly recommend her place to anyone staying in Zurich!
