Mario was really helpful in making sure he met us on time and the location of the apartment was perfect, tucked away in one of Port's winding streets, but very central and an easy walk to the station which made a huge difference with our heavy suitcases. The apartment was exactly like the photo and spotless, and perfect as a place to leave bags, get a good sleep - and explore Porto. Felt the security was good too. We will be staying here again for sure.
