Isi's home is centrally located and a very comfortable stay for a solo traveler. It's a 2 minute walk from the train station where you can easily catch a train or bus to the airport. He lives in the apartment with his wife and kids, all of whom are very friendly. Isi and his wife gave my friends and I a lot of great local tips (like where to get the best fondue without paying extortionate tourist prices!). He's very knowledgeable about Geneva, the rest of the country, and Europe in general.
