We spent a lovely week in Alice's flat which is spacious and clean with a wonderful garden in a quiet street only a few minutes walk to the city centre and the beach. Sant Feliu is a pretty village with a lovely old fashioned feel to it and the coast is wonderful with beautiful coastal walks and many coves and smaller beaches. There is a market with fresh produce daily in the city centre and lots of restaurants and tapas bars. Girona is 30 minutes away with great shopping (shoe shops!) and a beautiful walk along the old city walls. There are mosquitoes in the summer, so do come with some repellent if you don't want to give your blood!
Watch out that the indoor parking space is quite difficult to get into (we gave up with our rather large car)... thankfully it is very easy to find parking in the street at anytime.
