Mafalda was absolutely great! She always got back to me really quickly, before I arrived she gave me information about the apartment, surrounding area, and how to get there from the airport. Once we arrived she was kind enough to offer us a ride from the metro station. The room was very clean, the house was spacious, beautifully decorated nicely located in a quiet neighborhood. Located near the river and in between the city center and the beach. Convenient buses that takes you to all the main sites to see. Mafalda also spent some time with us orienting us about Porto, places to visit, and offered us maps and other guides for our stay. Overall an awesome experience. Would highly recommend staying with her.
