Getting to the Conference Venue from the Airport
Getting to the conference venue by metro is convenient, fast and cheap – a 25 minute trip every 1/2 hour from the airport to the main town. At the airport take the purple line (E) until you reach the Trindade station, where you should switch the yellow line (D) and stop at Sao Bento station. (For the whole trip you need a Z4 title that you can buy from the machines; buying it first time you also get a ANDANTE AZUL card; keep it for the way back or other trips that you wish to do in Porto).

To get to and from the conference venue to other parts of town the most convenient way is by taxi/uber. Downtown can be reached in a 5 to 10 minutes trip. From downtown then metro and bus are arguably the best alternatives.
A nice option to get around along the Douro river, from Alfândega do Porto, Ribeira, Foz including the neighbour cities of Matosinhos and Gaia, is to rent a bike. Several rental shops can be found around the area of Ribeira.
