My friend and I had a superb stay at Jean-Phillip's. Their apartment is situated on a private floor and is an easy walk from the train station and fairly close to the old city center. UN is only two tram stops away, about a 10min brisk walk. Although we only stayed there for one night, they still provided us with detailed city info and a really informative audio guide, my friend used to live in Geneva and it even taught her a lesson or two. It's my first air bnb experience and I totally felt at home. Highly recommended and thank you!
