On the Costa Brava there are plenty of hotels and private houses to rent. However, the end of August is still high season and the coast is very popular, so you should not let too much time in the election.
We would recommend the following places:
Blanes
A Spanish port and in the immediate vicinity of the venue.
Recommended for anyone who only stays for a few days.
Our second / third home if you will. A small urbanization with a beautiful beach. The convent takes about 20 minutes but that's worth it. If you stay longer is absolutely right here.
