Nice, clean apartment with bedroom, living room with table and mini kitchen and bathroom. Even a small balcony.
They welcomed us and explained us a bit about Porto, sights, transportation,...
Good location, safe environment, walking distance to city centre, some nice bars close by. Close to metro with direct connection to the airport.
Unfortunately, the people in the apartment above us were quite loud. But this was the only not so good thing and this always depends on the current guests.
