While we never met Mario, his place is incredible and highly recommended to stay at. My girlfriend and I were in town for a night to see the football match at the Estadio do Dragoa and felt right at home. It's right next to the Bolhao metro station, a stones throw from the downtown, and not terribly far from the river. The bathroom was nice with everything laid out for us, and the room was perfect. Also, the complementary breakfast nearby is a must. Highly recommend staying here!
