Went on a week's ski trip to Puy St Vincent with two children. We last cane here in 2011. We booked through Snowbizz who use the hotel for their families. Snowbizz are brilliant and the most child focussed ski providers out there, nothing is too much for them.
Booking in was no problem, once we arrived we got our keys and passes immediately and had been told where things were. This helped us get a sneaky extra hour on the slopes.
The rooms are basic, but considering we were on the slopes all day, basic is as much as we need. It's a self catering hotel, the supermarket is 2 minutes away.
The good bits:
Hot water and heating were spot on, hot bath always available for four people.
Beds were comfortable.
Bad bits (though no real biggy).
Our room had no oven. There was a microwave, but this did limit to what we could cook.
There were food items were a bit random , we had 2 mugs but 16 glasses??
Wifi is terrible, particularly between 5-8pm where the whole hotel is probably trying to access it, but it is free.
These make it a 4 rate and not a 5, but generally a very good stay.More
