Sylvie's place is lovely and has great views of the lake and local vineyards. Beautiful spot. It may be close to a main road, but you don't hear much of this from the room and it doesn't really impact the view.
Sylvie was really quick responding and have us a very warm welcome. She also provided some tips and passes for public transport, which is a nice touch.
If you have a car or don't mind taking the bus/train, this is a perfect spot from which to explore anywhere around the lake. We were sad not to have more time here!
