We really enjoyed our stay in Porto. The apartment is within walking distance of the river , port caves, many restaurants, shops and Sao Bento train station. It is in a narrow cobbled street in the old part of the city where everything is either up or down hill so be prepared to walk everywhere which is the best way to discover all the hide local places. It is a short walk to get the bus # 500 to Matosinhos and the beaches on the Atlantic Ocean and the fresh fish restaurants where it is all cooked outside on the street.
The apartment was clean and comfortable and certainly adequate for our needs.
