The apartment is very charming and in a great location if you want to visit Porto and the Douro valley. There is great humidity in São Félix da Marinha (the proximity to the Atlantic ocean), which can be noticed also in the apartment (the walls get humid very quickly), but nevertheless the amenities and the cleanliness of this place are a great plus. The host is very helpful and eager to attend to all your questions. A really nice place to use as a base for exploring this part of Portugal.
