We had a great stay in Silvana's apartment. Her apartment is cozy but spacious enough for 4 people, with a great view of Lake Geneva from balconies. Parking was easy to find on the street.
Silvana was very welcoming, and made available everything to make our stay comfortable (even a cot for our son). Communication was also great, and Silvana replied almost instantly to my messages. I definitely recommend Silvana's apartment and herself as host for great stay in Lausanne!
