Lovely place. We stayed for just over 2-weeks and this flat has pretty much everything and is really well maintained.
Separate bedroom with two singles (you can rearrange to create a double) and then the usual living room sofa bed - loads of bedding and blankets provided (but bring your own sheets and duvet/pillow covers).
Fully stocked kitchen - pans, utensils, two different coffee machines (drip and capsule), dishwasher, and even a raclette/fondue machine. Plus, actual cleaning products provided - lots of flats expect it left clean but don't provide the materials to make it that way.
Separate toilet and shower rooms - great water pressure and plenty of storage for toiletries.
Balcony looking out over Bourg Saint Maurice and the mountains with a couple of chairs.
There's a locker downstairs for snowboards, skis, helmets, boots, etc. so that keeps the place tidy.
Internet is fast enough for two people to do simultaneous video calls.
Location wise it's a short walk to the bus station and lifts, only a little bit further to the supermarket, and loads of restaurants to choose from in 1800.
Note, the pool isn't operational in winter.
Overall, I would fully recommend and Olivier is super easy to communicate with.
