we have booked the same place as we did for the classic, domaine long pre
it is a sort of country park near stavalot (kind of centre parks) chalets were basic, but not in them apart from sleeping really and the reception area has a basic restaurant and reasonable bar. The park is very rural and some facilities like swimming pool. main advantage is it is cheap got a 4/6 person chalet for 4 nights for 200 euro,s we will go thursday but might go back sunday or monday 4th night was basically free.
