daniyke,
check out Porto and Vila Nova de Gaia. (across the river from Porto). We live in the Porto district, Rio Tinto. The Metro stop is 4 minutes from our building. From there we can go anywhere.
Porto and Gaia have a good Metro and train system, and an international airport. Pick somewhere close to the Metro. The beach is 10 - 20 minutes by car. You can take the Metro to Matosinhos, where you'll find wall to wall great seafood restaurants down by the water.
Not too hot in the summer and not too cold in the winter. Often a nice breeze to keep things cool.
p.s. I'm NOT with the chamber of businesses. LOL. We love it here!
