Here you will find information how to reach the conference venue hotels from the Belgrade International Airport Nikola Tesla.
The easiest way to get to your hotel from the airport is to take a taxi.
For the use of taxi services from Belgrade Nikola Tesla Airport to any destination in Belgrade area and further, please contact the city service TAXI INFO desk, located in the baggage reclaim area. Detailed information is available at http://www.beg.aero/to_&_from_the_airport/taxi/from_belgrade_airport.327.html.
From the airport, it would take around 10 minutes to get to the conference venue by taxi. The fare is 1400 RSD. You can check the fares for taxis from the Belgrade airport at http://www.beg.aero/upload/documents/20140318-Taxi_zones.pdf.
Yet another possibility is to take a city bus. Bus 72 goes from the airport to the place called "Zeleni Venac" in the city center. This bus has a stop near the conference venue.
