    Event Venue

    "Cero + Infinito" Building - Ciudad Universitaria, Buenos Aires City

    Ciudad Universitaria, Buenos Aires City

    The conference will be held in the School of Sciences of the University of Buenos Aires, located near the "Belgrano" neighborhood. This area contains many hotels and is well connected with the rest of the city.

    Getting around in Buenos Aires

    Nearby hotels, touristic information, and general tips

    Arriving at Buenos Aires. Buenos Aires has two main airports, the Ezeiza/Ministro Pistarini International Airport (EZE) and the Aeroparque Jorge Newbery local airport (AEP). The international airport (EZE) is quite far away from the city, so you must take a bus, a taxi, or a "remis" (a rented car with chauffer) in order to get to your hotel. There are companies providing shuttle services from both airports to the city (as, e.g., this one), you can hire their services directly at their booths in the airports. If you arrive at the local airport (AEP), then you can take a taxi or a "remis" to your hotel, it should be a short ride.
    Accomodation. We recommend staying in the "Belgrano" neighborhood (which is this area). You will be within walking distance to the university while being connected to the rest of the city (e.g., a 20-minute ride through the subway line "D" takes you downtown). You can find many hotels in this area, and it is also possible to rent a flat for some days. It is also possible to stay in downtown Buenos Aires (there are many hotels in this area), however please take into account that you will be quite far from the conference venue.
    Getting to the university. If you are located in the "Belgrano" neighborhood then you can walk until the conference venue. Please take into account that there is a highway separating the university from the rest of the city, so you will have to plan your trip in order to cross the highway through one of the two available bridges. You can also take a taxi or a bus. If you want to take a bus, the 107 bus will take you from Belgrano to the university and back. In order to take a bus you must first buy a "SUBE" electronic card in any of these places (it costs ARS 126, or about USD 1 at the official exchange rate) and pre-charge it with some money. The "SUBE" card is not personal, i.e., many people can get on a bus and pay with a single "SUBE" card. Taking a taxi is easy in Buenos Aires, but there are not many taxis available at the conference venue, so be prepared to take a bus or to call Uber or a similar service back. Mobility providers as Uber, DiDi, and similar companies are available in Buenos Aires. If you stay in downtown Buenos Aires, then you will have to take the 45 or the 33 bus in order to get to the university.
    Weather and tourism. December in Buenos Aires is warm and sunny, so expect temperatures above 25 degrees Celsius during the day. Packing a light coat and an umbrella may also be a good idea, just in case. There are many restaurants and cafes in Buenos Aires, and plenty of places to visit (you can check the official touristic webpage for more information). If you are a football/soccer fan, don't worry! On Tuesday, December 13th and Wednesday, December 14th we plan to finish the sessions early enough in the afternoon so you can watch the World Cup semi-finals. And if you are not interested, then you can enjoy an almost empty city during the matches!
