We had a woderful time at luiz apartment. It is quite far to walk from the historical city center but there is a very good connection to the center by bus (500) or the historic tram line, which is fantastic. Therefore the atlantic ocean and the douro are just a 2 minute walk away. That might be the reason for the dampness in this beautiful, old house. Communication with luiz very good. He gave us a lot of helpful information about the quarter foz and porto.
