Hugo's studio by the lake is such a pretty spot, and a perfect starting place for exploring the valley. Plus, it's accessible by public transport and you can walk to the shops, which isn't a given for other places in the Vallée de Joux. Hugo was welcoming, friendly and helpful with ideas for hikes. Plus, if you are brave enough, you can go for a dip in the beautiful lake all year round (I went in late October and it was great :).
