We travelled as a couple with our 1yr old daughter and José's apartment was excellent, lots of space for her to roam about and the decking and terrace area was a great addition.
We were met by José's friend Joáo who checked us in and offered some tips and advice for our stay. There was also a much welcomed bottle of local wine! The apartment is about a 15 min walk from most of the major sights and there are some great bars and restaurants within a few mins of the apartment too.
On checkout José even dropped everything to come our rescue when we left some bits behind in the apartment - would definitely recommend to anyone staying in Porto
