We stayed at Joao's place for 5 days in Porto. The apartment is very nice inside with gorgeous views of Porto bridge from the living room and bedrooms. Joao was also very nice; he picked us up from the train station on the day of our arrival. Joao was extremely reachable and helped us throughout during our stay. On our day of departure, he was kind enough to stop over early in the morning so that we had no difficulty in taking our luggage out and booking the cab to the train station. Overall Joao is a superb host and the apartment was nice as well, with the only caveat being one has to navigate a flight of stairs up & down while entering or getting out of the apartment.
