If you are looking for something basic and cheap, but still pleasant in Val d'Isère, you might as well try out this small hotel. I slept here for one night only and found it nice, especially considering how expensive everything is in Val. It is located at the beginning of the old village, I'd say 150 metres from the Tourist Office; you can easily walk to the slopes or take the frequent shuttle to Rond Point des Pistes (passes every 4 minutes, 1 stop only!).
Rooms are quite clean and cozy enough (apart from the bad spring mattress, but I've always found bad mattresses on the French Alps). I stayed in a single room with basin, shower and bidet, with a toilet on the same floor to be shared with three more rooms. The lady at the reception is very nice and helpful, which is definitely a plus! There is also a restaurant in the hotel; I had a fondue there, which honestly wasn't too good, but not too bad either.
Keep in mind that if you book through the Val d'Isère official website, rates will be quite higher; the Tourist Office proposed me the same room for 70€, but I went directly to the hotel and got a much cheaper price, 50€ per night incl. breakfast (a small and simple sweet buffet) in low season, while double rooms are 70€.
