The Hotel is located in the city center of Mons. The location could not be better in that regards. Parking is free, so that is another big plus. Staff members were helpful, but not at all were friendly or understanding. The Wifi is not accessible beyond the second floor, and the lobby closes at 10pm. They have a conference room on the first floor though- so if it is available - they can be accommodating.
Breakfast was simple, but good enough for what you're paying (Cold. Cereal, bread, cheese, ham, yoghurt, muesli, and 2 choices of juice). In regards to reception, they are also not available by phone beyond 10pm (regardless if the automatic reception message says they will be with you shortly).
In regards to the hostel itself, it is in good conditions and clean. The rooms not so much. The mattresses very clearly need cleaning. Colleagues and I all had sleeping difficulties due to dust allergies. Space is very limited in the rooms. There is less than 1.5 Meters of walking space between the beds. Also, there is a primary school located behind the hostel, so expect to hear school bells and children playing outside Mon-Fri around 7am to 8am if you are facing the back-side of the hostel.
Summary: Great place for the price. If you are young and don't care about comfort and space- take this hostel and you'll be very happy. If you are less of the "Bunk-bed hostel" type, pay a bit more and go elsewhere.
