The apartment is a great place to stay in Besalu and get to experience the town.
We enjoyed having breakfasts on the little balcony (with fresh bread bought every morning from the local bakery!) and watching the street life below.
While it's just off the main square, it does feel very quiet at night and because it's north-facing it stays quite cool on hot days as well, which means sleeping was no problem.
The kitchen and bathroom were nicely equipped as well, so we cooked a meal with ingredients bought on the local market (every Tuesday).
Besalu has a nice mix of little restaurants which allowed us to try something new every day (Curia Reial - with a nice terrace overlooking the bridge - and Quina Llauna - tapas bar on the main square - were our favourites).
During the day the town is busy with tour groups, but at night it quietens down a bit and you do feel more part of the local community.
