Most people visit Bruges for a day. You are staying, which means you get the version of the city that the day-trippers never see. Here is what the next 24 hours look like from your base on Langestraat.
Check in, use the luggage storage to travel light, connect to free Wi-Fi, and lock your valuables away in the hostel lockers. Then the rest takes care of itself. Cobbled streets, canal paths, Belgian beer. The Bauhaus gives you everything you need to get on with it.
