Mario’s place is comfortable, spacious, good located and cozy. If you don’t exactly know what you wanna see, you can always use an App made by him, which includes sightseeing routes, main monuments, restaurants and bars. Towels are provided, wifi works nice, you get own key to your room. At night room can be a little bit cold because of small heater and big space but depends on person and current season. Apartment is located close to city center and also near to metro and bus stops. Kitchen with all staff and washing machine, nice bathroom. Communication with Mario is very good and he will answer your questions fast. I recommend this place for staying and enjoying Porto and recommend Mario as a host.
