We had a great time at Paula's apartment. Everything was as, or better than described. Paula met us at the apartment and gave an extremely thorough and helpful overview of things to do in Porto.
The apartment is tastefully decorated with lots of quirky vintage pieces - including a fully working radiogram.
The location is excellent, we walked everywhere and the subway back to the airport is a couple of minutes walk from the apartment.
To top it all Porto is such a great City full of friendly people and amazing experiences. Go go go.
