I can wholeheartedly recommend Jacques' place! The flat is very comfortable and very well equipped, there's everything you need for staying a few days or longer. The view from the patio (and bed) is fabulous. It was so nice sitting outside in the evenings watching the sunset. Yes, the motorway is nearby, but I have to say that it didn't bother me at all (and I am quite sensitive to noises). You can hear it, but it's rather a constant background noise, easy to blend out. Inside the flat it is absolutely quiet.
Blonay is a pretty village, a great starting point for visiting the lake and its surroundings. With two train stations not too far away you won't need a car to get around. The local Migros is also only a 15min walk away.
All in all I had a good time at Villa Escondida, and I am looking forward to my next stay. 🌞
