We had a great in time in Porto ! The apartment is well located, clean, and spacious. There could be improvings in terms of storage in the rooms with shelves for example.
Regarding the transfer proposed, we were informed that it would take more than 1 hour to go from the airport to the appartment by metro. We were disappointed to learn that this information was false and that the trip from Trindade to Airport takes 20 minutes. Knowing that, we would have probably taken the metro.
