I truly recommend Camping Sant Pol, a delicious, shadowy, cosy bungalow park situated only 300m from the beautiful beach of s'Agaro. Meant for families with small children, they organise activities for the little ones, besides their facilities and surroundings are outstanding. Quiet too, and with over 1000 different species of flowers and plants.

I enclose the link if someone is interested:
Camping Sant Pol, Bungalow Park, Sant Feliu de Guíxols, Costa Brava, Girona
Glamour Camping, or Glamping on the Costa Brava as they rent cool wooden bungalows with plenty of facilities... By the way, food is excellent in that area!
