Warning, it is 366 steep, winding steps up. However there are landings and displays at several points along the way. Good views of city from top, but plan to stay about 1/2 hour to hear the carillon bells from right next to them. Startlingly loud, but not deafening. The sound of the bells is beautiful when you are right there. Frequent free concerts in the back courtyard.
Nice breakfast, good bar/restaurant on the side, 8 mins walk to the belfry of Bruges, 13 mins walk to train station, close to everything, food and shops all around, nice shower. Perfect for a short stay.
