If you’re flying to Lisbon and heading straight to the venue the best way is to take the subway on the station underneath the airport. The venue is just 3 stops away (hop off at Oriente station) and it takes around 10 minutes.
If you’re coming from the city centre you’ll probably find a metro station nearby. Since it’s not a very big network (4 lines in total), it’s quite easy to make the necessary connections.

Where the subway doesn’t reach there’s a bus. Tickets for both are interchangeable and you can get them on vending machines on the subway. A ticket is just €1,85 (there’s a first-time 50 cent charge for the reusable card) but you can buy several tickets at once or muti-day passes to get some savings. In either case, just head to Oriente Station.

If you’re coming by train, then stop at Oriente station and you’ll be at a 8-minute walk from the venue (600m).

A taxi can be easily hailed from the street or from specially marked bays. Taxis are fairly cheap and will get you around the city for around 5€ to 10€ a ride. Uber has a very strong presence in Lisbon but fares are quite similar to taxis. If you already use it back home then you just need to have data on your phone to use their app.
