Had a very nice 3 night stay here last week. Apartment was clean. No street noise as the apartment faces the back of the street but you still get a decent view. Bright and spacious with lots of natural light. Francisco checked us in and gave us some local bar and restaurant suggestions, two of which we checked out and had an amazing meal/drinks at. 5 minute walk to the Sao Bento train station. Centrally located if you want to see all of the major sights, and close to the downtown shopping area as well. A stone's throw away from the bridge to cross to Vila Nova da Gaia where you get amazing views of the city. And of course all of the port wineries! Would definitely stay here again if I go back.
