Venue

The venue of the FLC-15 conference was Hotel DAP***, Vitezne namesti 4/684, 160 00 Praha 6 – Dejvice.

The venue was conveniently located at the Metro (Underground) station Dejvicka (green line A), in a close vicinity of the Prague Castle.

City of Prague

Prague, the capital of the Czech Republic, is well known for its historical monuments, classical architecture and rich cultural heritage that continues today in many theaters, concert halls, opera houses and galleries. Come and discover this wonderful city and walk in the footsteps not only of Franz Kafka and Antonin Dvorak but also of Tycho de Brahe, Johannes Kepler, Bernard Bolzano, Christian Doppler, Albert Einstein, Jaroslav Heyrovsky, Vladimir Prelog and others.

Transport from Prague Airport to the Conference venue

Public transport

Bus 119: Prague Airport (Letiste Vaclava Havla) → Nadrazi Veleslavin, then take metro to Dejvicka station (2 stops). The journey takes 30 minutes. Bus stops are situated directly in front of both airport terminals. There are two exits from Dejvicka metro station. You can take the exit with non-moving stairs and follow the sign “Smer: Vitezne namesti” (there is a lift behind the stairs). After leaving stairs or the lift in the vestibule, turn to the right and follow the same direction signs. After climbing another non-moving stairs and turning right, you will see the building of hotel DAP.

Prague public transport is fast, efficient and frequent. Metro and most daily trams and buses operate every day from 5 AM till midnight. Night trams and buses (line numbers beginning with 5) operate throughout the night. Similar to most capitals, the concentration of picpockets is elevated, be aware in the historical centre as well as on your route from/to the airport.

Tickets:
Basic fare of 32 CZK (approx. 1.20 EUR) entitles the holder to use all means of public transport (Metro, trams, buses and cable car to the Petrin hill) for up to 90 minutes including unlimited number of changes. Cheaper fare of 24 CZK (approx. 0.90 EUR) entitles the holder to use the public transport for up to 30 minutes (daytime only; cheaper rate does not apply in night trams/buses). The ticket must be validated using a yellow box while entering the first bus or tram, or while first entering designated area in Metro. After validation, just keep the ticket with you.

Tickets can be purchased at:

• Public Transport counters in Arrivals Halls of Terminals 1 & 2 (from 7 AM till 10 PM). Recommended option.
• Ticket machines situated at the airport bus stops. New machines accept cash or card payment, older ones accept CZK coins only. Recommended option.
• From a bus driver (petty cash required). Please note that a ticket purchased from a bus driver costs 40 CZK and the passenger should pay by coins or nominally small banknotes.
• In the city, tickets can be purchased at newsagents, tobacconists, hotel receptions, ticket machines in Metro entrance areas etc.

When entering the bus, remember to validate the ticket.

Taxi (AAA, Radiocab)

The journey from the airport to Vitezne namesti (Dejvicka metro station) takes less than half an hour and should cost around 400 CZK. The taxi rank of both official airport companies (AAA radiotaxi and Radiocab) is situated directly in front of the airport terminal. For the journey back, we strongly recommend ordering a taxi from your hotel reception rather than finding a cab in the street.

Transport from railway stations to the Conference venue

All principal railway stations are situated along Metro stations. There are only 3 Metro lines in Prague (A, B, C) so it is not difficult to reach Dejvicka station (terminal of the green line A). There are two exits from Dejvicka metro station. You can take the exit with non-moving stairs and follow the sign “Smer: Vitezne namesti” (there is a lift behind the stairs). After leaving stairs or the lift in the vestibule, turn to the right and follow the same direction signs. After climbing another non-moving stairs and turning right, you will see the building of hotel DAP.
If you decide to take a taxi, we strongly recommend ordering one rather than finding a cab in the street. For AAA radiotaxi, just call 14014 and wait 5–10 minutes until your taxi (yellow colour) picks you up.
