We've just returned from a stay here. Its about an hours easy drive from the circuit de Spa Francorchamps and about 20 minutes from the beautiful village of Monschau.
The 3 bed room we had was perfect. Very comfortable and very clean! A huge double bed and en suite at one end, with a single at the other. The only change I would make is to add a kettle and some teabags. Breakfast was more than sufficient, with enough variety for even the most fussy of eaters. We even had the option to take a small packed lunch away with us too.
The owner had limited English but this was never an issue.
I would definitely return here with an aim to explore some of the beautiful forest surrounding it.
