Visited one night back from wintersports. The week before we stayed at F1 Bourg-en-Bresse where it was very very dirty. We had a big stain of blood on a blanket. Shower was overflowing, not letting the dirty water out. Showers were not clean there and the toilets were not clean either. So you may understand that the contrast was very very big. Dyon Nord was clean, anything working allright, personal was friendly.......what more to expect in a F1 hotel. This was first-class F1!
