Another good place to start looking for a Girona apartment rental is the tourist information centre. They have a list of apartments within the centre of Girona that are rented out specifically for tourists. They also have an official brochure from the ATA (Tourist apartment association), that lists apartments for rent across the province, together with colour photographs and contact information for each apartment.
If you are already in Girona, then keep an eye out for signs hanging from balconies that say 'for rent' or 'Se Alquila'.
