I am going to Tossa de Mar in July. There are some great picture and I have been recommended it by quite a few people. It's a very pretty place, but is still reasonably busy in summer, but not commercialised like Lloret.
For some nice pictures and description:

We went a few years ago for the day and it looked really pretty. The restaurants are supposed to be very good.

Hope this helps!

If you want a lovely pretty and quiet place look up calella de palafrugell it is wonderful total chillout, and the very pretty llfranc next door , you walk the coastal path with lovely views go on to the costa brava photo gallery to see some, and try this link if it does not work just type in palafrugell webcam and you will get a link
