We had an awesome time in Porto and Catarina and Alexandra were exceptional hosts. They gave us really good tips on food, nightlife and so on. Even picked us up with the car because it rained! Their house is beautiful, spacious, full of light and EXTREMELY clean. So is the room, and the bed is really comfortable. It is located in a nice area in/close to the centre. It-s all walking distance. Maybe a bit humid in this season. Would definitely recommend it and hope to visit them back.
