Stayed overnight here and also left our MWB van here and took the train into Charmonix for less than 2€. Train station 1 min walk away and out van was safe all day. Train passes a couple of times an hour during the day but very little noise and silent at night. Public toilets 5 min walk away and felt very safe. Great place to park when visiting Charmonix centre due to the lack of car parks without height restrictions.
