Antonio's place is in a good location, about 20-30 minutes walk from the city center. There is a bus stop right behind the residential building and the subway station is about 5 minutes walk. The apartment itself is very cozy and spacious. We had a nice stay there.
Antonio is a great host. He was very responsive when arranging the stay. He met us personally when we arrived. When we were leaving our flight was very early in the morning and Antonio arranged a van for 7 people to transport us to the airport at 4.30 AM. Antonio has prepared a nice book of tips for what to visit in Porto. And he even had prepared some food when we arrived.
Antonio, thank you very much for the nice stay in Porto.
I definitely recommend his place.
