We thoroughly enjoyed out few nights at the Hotel Trois Luppars. The staff were always kind and polite, helpful and spoke some English which helped. The hotel was very easy to find, located on the main Grand Place. We parked in the main square - without buying a ticker. We took the risk. You should buy a ticket during the day but free overnight. There is a large car park under the square which we used one night when all cars to be removed from the square. We were in an annexe at the rear of the hotel - a lift gave access to the rooms. Rooms were fairly small but very clean. Bathrooms particularly small but clean. Very, very quiet at night.
Plenty of excellent restaurants on the square for dinner.
Breakfast was fairly basic. Ready plated on a tray it consisted of bread rolls, jam, cheese, apple, yoghurt, etc.
Highly recommended - we would certainly go back.
