Stayed with friends as we were attending the belgian grand prix at Francorchamps, Spa.
In all it was a very nice hotel. Staff were friendly and spoke good English. Communal areas were nice and welcoming. Rooms were quite basic but clean, with comfortable bed.
There were guests from all over Europe and I have never stayed at a hotel with such a nice atmosphere with "Entente Cordiale" between them. Ate in the restaurant our first night, due to convenience. Buffet meal, not best quality but filling!
Be sure to visit Monschau if you have time. Very pretty, traditional German small town.
