We stayed at this property over the UK February half term. We were 3 adults and 3 kids. The flat is cosy. Has everything you might need while on a self catering holiday. There is a Spar shop just outside the property , which is great for fresh baguettes, milk etc in the morning. The shop is outside level H (where anyway you keep your snowboards and skis as the locker is situated there).
Belle Plagne is beautiful, small Alpine village.
We were a group of snowboarders and skiers and I personally find the area too flat for snowboarding.
I think the resort is great for beginners to intermediate snowboarders/skiers but fantastic opportunities for off piste if you are advanced. We had the whole area ski pass but we found the links to Les Arc a bit too long and there was a 2-4 km flat cross country on route to the Vanoise Express we didn't know about and it just took too long to get there. I suggest you to stick to La Plagne only if you have just a week there.
The glacier above the village is closed when there is a low visibility. We were lucky to have 2 days in which we could go out the Traverse and snowboard the Rochu and the rest of the slopes there, which were a nice challenge. The views from the glacier are simply breathtaking so it is really worth going up there.
All in all I highly recommend the property and the resort. We had fantastic fun.
