I was met by Carlos's daughter in law who was very friendly and she kindly showed me around the apartment and went through the map of Porto with places to visit & local restaurants , bars and hidden gems. She gave me some good local tips and Carlos kindly left a nice bottle of port which was a lovely gesture. The apartment was lovely, new, modern and well equipped with everything I needed. Porto is very compact with good transport links and very walkable. I throughly enjoyed my stay in Carlos's apartment and would visit Porto again.
