Carlos was a great host. He gave me very precise information on how to get to his place from the airport and was very quick to answer any questions I may have had before my arrival. When I did arrive, he took the time to talk to me about the things to see/do in Porto and this enabled me to visit places I otherwise would not have known about. In itself, the apartment is very well located and clean and the room was very nice and comfortable. I would definitely stay there again!
