We had such a lovely stay in the apartment. It was perfect for us and our young daughter as it was quieter in the evenings, with a play park nearby, and walking distance to old town. We highly recommend the Chicano cafe, and restaurant around the corner, both so lovely and locally priced.
The metro stops nearby are well placed and we could get everywhere we needed in Porto using them, or by bus. We went to the sea life centre, and did a river cruise which were both enjoyable and great for kids.
The apartment was well equipped and had what we needed for a short city break. Would recommend it for young families.
