Toni was extremely helpful and always took the initiatives to get in touch. When I arrived, his father helped me settle in and showed me various places to park the car for free (very useful local knowledge). The flat itself was very clean and had a good location in central Girona - very close to the old town and various restaurants.
One day before checking out, they also got in touch with me first to work out timings and logistics. In all, I would recommend anybody visiting Girona to stay here!
