We have 4 kids of which the youngest is 5 months, so we were looking for a comfortable place to stay where we would have all ammenities, could spend days in a row without having to go places to entertain the kids.
ChaletZep with has a pool, sauna, great outdoor playing space for the kids, a TV room, great fireplace and enough bedrooms to even fit in my inlaws at the same time which was ideal! The two oldest kids went in the pool twice a day, we sat hours at a stretch on the terraces, at night we lit the fireplace and enjoyed the unbelievable view on the Swiss mountains.
We had great walks in the mountains, at least 5 good walks start from the village Les Collons. We bbq-ed at night, cooked dinners in the well-equiped kitchen. We had a great time, very relaxed with 4 young kids, and returned feeling healthy of the Swiss mountain air, outdoor life and enough rest. This is really a very great place to stay and we will definetely come back, even better if the kids are bigger and can join on walks etc.
