For anyone visiting Porto, this is the perfect flat - location, comfort, design, and the host are absolutely perfect. Joana is extremely responsive, and her sister Ana, who greeted us as Joana was away when we arrived, was simply lovely to work with She even walked through a map of Porto with us, circling things to see during our short visit and explaining how to walk to key sites. As we arrived during the first cold spell in Porto, the apartment was cold and we asked Joana about the heat. She responded immediately and very friendly, and explained that it might take a bit of time to warm up. Indeed, after giving it some time, the apartment was the right temperature and we really appreciated her care and responsiveness when we inquired about the heat. The apartment is simply beautiful, and in a location with perfect walking access to restaurants, pastelarias, and major historic sites. Thank you, Joana and Ana, for a being wonderful hosts and for helping make our stay really exceptional in Porto.
