We spent 2 nights at Kiki and Teresa's apartment in Porto. The place and the location were really great and we could enjoyed the city, not only of the sightseeings, but also of some "local" places recommended by our fantastic hosts .
Kiki and Teresa came with a map of the city and located all the places a foreign need to know to have a real image of the city. They are really friendly and have a superb willingness. People who will travel to Porto have to know them. We will return as soon as we can :)
