As suggested, it can be pot luck with the quality of the cabins. A few years ago we had one that was awful. So awful that when I sent some pics with a letter of complaint I was given a free holiday.
I was told that we's have been moved if we'd complained straight away.
I have to say that ever since they have been fantastic, other than a few ants in the kitchen area during the warm season, which is to be expected in the middle of a forest.
The 2 bed cabins do seem to be a safer bet if you don't mind paying the extra, although we've often booked a 1 bedroom and been upgraded on arrival with nothing said.
Reception is 24 hr, and generally very helpful. Housekeeping are excellent and will clean the cabin every day if you request, and will deliver clean towels, etc. immediately.
The pool is superb, and we've often had it to ourselves during the day.
The buffet food at the restaurant is also very high quality.
The shop is pricey, which is to be expected, but there is a MASSIVE supermark in Val de Europe which is 10 minutes away by car.
Would also recommend the Tree Tops Adventure at the entrance to the resort.
Have a great time!
