We stayed at the CdA the week after the Tour passed through AdH and thought that the flat was excellent. Having stayed on family ski trips in standard French shoe boxes it was a pleasant surprise to find that even the one bed flat was big enough for us and our two children. One was in a cot in our room and one in our bed. For older kids or 4 adults it would be more of a squeeze needing the fold out of the sofa- night owls on the sofa bed then.
The kit in the kitches was good and beyond adequate. Our chief problem was that a previous guest had burned out the kettle. We took it to reception n day2 and at least every other day followed up for a new one. We never managed to get another one which is pretty poor and we started getting questions about whether it really was broken (yes it was) and were we sure it hadn't been put in the flat (no it hadn't).
Other than that, good place to stay,a great spa and a great resort for summer sport.More
