Hey Dzub
you are going to have a ball there! Bring your 3.3 and 3.7!!
Eric is right 100%, if you want also waves there is another spot called "Bologna". You need a car if you get accomodation in town, the spots are 3/4 km out but nightlife is great and lots to do during the day if your wife does not windsurf. I used to spend few months every year there, the place its become more commercial and turistic that what it was used to be, but I still have friends living there and they still love it. If you need sails repair (I hope not) search for our friend Tania in town she run her own loft
www.tanjaemig.com/ she can help you out.
Re Mistral club, I think is between town and "la duna" on the strech of beach called "el porro". Anyway plenty of windsurfing gear there.
Best wind&waves and enjoy it!
Ciao
Alberto
