The apartment of Catarina and Alexandra is a perfect place to stay in Porto to visit and enjoy the city. The location is perfect, walking distance from the main touristic attraction, and also from the less touristic, that Catarina and Alexandra will suggest you. I found their advices very useful and detailed. The communication with them is excellent and they really care about their guests. The room was very nice and the apartment interesting because of its original details. I advice to choose the apartment of Catarina & Alexandra!
