Lovely apartment, nicely decorated and with a stunning view. The only pity for me was that there's never sun on the balcony and in the apartment. (But that might be a plus in the Summer).
The location is perfect for going on walks and hikes.
It's only a short drive to San Feliu de Guixols itself, it was very easy to park for free in the harbor and walk to the center. Balbina is a great host, will do her best to accomodate to your needs and the communication is great.
There's a small parking spot in the garage that comes with the apartment. For me it was just easier to just park on the street, which was easy to do (at least while I was there, off season).
