Me and my friend visited Porto last week and stayed in Susana and Alfredo's apartment for 1 week.
They are great hosts, they picked us up from the airport even our flight was late in the evening and before they brought us in the apartment they kindly done a short sightseeing tour through the night Porto.
The apartment itself is just perfect! It is very good located, big and equipped with everything what you need, moreover it is modern and new.
We highly recommend this place!
