We had an amazing time at Sandra and Pierre's chalet. In fact, the place is quite modern in its architecture and design, and with an amazing and unique view of the valley. It is also in the middle of the forest. All went well in the chalet.
There are plenty of things to do in the area, just don't miss going to Glacier3000, near Les Diablerets, it is a once in a lifetime trip.
The best restaurant among the many we tried is the Refuge de Solalex, great service and amazing food, with the hiking tracks just around the corner.
Definitely worth staying at Sandra and Pierre's chalet for an amazing visit of the region.
Thank you Sandra for your quick responses and advice.
All the best,
Ryan
