We enjoyed our stay in Porto - the flat was centrally located for all the attractions and very easy to get to and from the airport on the tram.
The apartment was clean and comfortable, with plenty of space and most things you would need, although the traffic noise in the bedrooms can be a problem for light sleepers. The drains in the bathroom also occasionally smelled because it is an older building but Jorge helped us deal with that.
Jorge and his family were easy to deal with and helpful when we contacted them during our stay.
