We stayed here for two nights while visiting the WEC round at Spa Francorchamps.
The owner was very friendly, but didn't speak English, so we communicated in poor French (mine) and Google Translated French (hers). We managed, though.
The apartment was comfortable for a few days at least and when we stayed had wonderful views across the valley.
My wife slept well, which is unusual for her, especially away from home, so this has to be a plus.
We didn't use many of the facilities, but there's a cooker, microwave, washing machine and (I think) dryer.
The nearby village of La Gleize provided a shop and the excellent Vert De Pommier restaurant, but in our short stay we didn't explore much further, which we both agreed was a shame as it looks a lovely area to spend some time.
