We travelled to Le Bon Abri on our Tour de Mont Blanc by mountain bike. The hosts are a friendly couple who make you feel at home and provide great service. Food was top and the breakfast served earlier than other places on our trip (a real bonus when you want to start early <7am). There are a selection of activities to keep you entertained in the evening (slackline, mini bouldering wall, boules, table-tennis etc). I would recommend this place to people travelling through the area. The beds and sleeping arrangemends are very comfortable.
If you are travelling by bike there is secure bike storage which is a definate advantage over other places.
