Everything was really nice and clean, nice flat where you have everything for short or also for long stay. Communication was also perfect, also when we had late flight, we could get to apartmant late at night. Great location - center, everything is close from the flat. On the other hand, there are lots of bars and noisy peoply on the streets. If you want to go on the party, see the nightlife in Porto that's perfect place, because from the party is close to get to the bed, but also you can hear the parties from the street.
I can recomend Patrícia E Bruno and her apartment :)
