We presume you are flying into Lisbon Airport (LIS), if you need other directions, please inquire.
The most obvious option to get from the airport to the conference venue will be by metro (fares, in English). Tickets are loaded onto a contactless card called «viva viagem», they can be bought at the large, blue vending machines inside the airport station. We recommend charging 10€ onto the card under the «Zapping» option. Note that there is a charge of 50¢ for the card, that can be recovered if you return the card undamaged together with the receipt.
The buses and trams in Lisbon (Carris) are on the same fare system, so the viva viagem works on them as well.
The meeting will take place in room PA2 (floor -1) the Mathematics building on the Alameda campus of the Instituto Superior Técnico, Universidade de Lisboa:
Pavilhão de Matemática
Instituto Superior Técnico
Av. Rovisco Pais
Building 24 on this map: (note that up is west)
How to get there
The campus of Instituto Superior Técnico (IST) is easily reachable by metro from the airport (it's around 20 minutes): take the red metro line and exit at Saldanha to Av. Duque de Ávila or exit at Alameda and go up the hill. Subway journey on Google Maps.
