Good appreciation! I do not remember any large balcony the Bruges, all were small and glazed but most of the houses, especially the most modern, had large windows that you could almost confuse with shop windows, many of them were carefully decorated. In my hometown there is also a habit of having a good time on the balcony when it is hot and, if this is not available, people usually take chairs to the street to take advantage of the evening breeze. Bruges is full of fantastic parks crossed by canals and surrounded by nature, I think that for its inhabitants it is their most usual option.
Thank you for this great comment @mindtrap! 🙂
