Very nice and modern little apartment in the center of Porto! It has everything you need for a good vacation, even if you'd like to be "self-sufficient" and eat in the apartment :)
There was only one downside of being located in the city center: during the weekend nights, it was pretty loud, as the windows are quite thin and don't offe good sound muting to the outside... Yet if you're planning to go out to party yourself, that shouldn't bother you!
