ACCOMMODATION

TRANSPORT

Public transport

How to reach the Institute of Macromolecular Chemistry

From the Komenský Hall of Residence, go downhill to the tram stop "Hládkov" and take the tram No 8 (in the direction LEHOVEC). Get off at the next stop ("Vozovna Střešovice") and change for tram No 1, 2, or 18 (in the opposite direction, PETŘINY) as far as the terminus PETŘINY.

From the Academy Residence, take tram No 25 (in the direction VOZOVNA KOBYLISY), get off at "Hradčanská" (2 stops), and change for tram No 1 or 18 (in the opposite direction, PETŘINY) as far as the terminus PETŘINY.

From the city centre, take the Metro green line A as far as "Hradčanská" station. From there, take tram No 1 or 18 (in the direction PETŘINY) as far as the terminus PETŘINY.

How to reach the Komenský Hall of Residence

How to reach the Academy Residence

From the Institute, take tram No 2, get off at "Vítězné náměstí" (9 stops), change for tram No 25 (direction to PODBABA), get off at the next stop ("Lotyšská"), take the first turning to the right, and go forward to the Na Marně Street.

From the city centre, take the Metro green line A to "Dejvická" station. From there, take tram No 20 or No 25 (in the direction PODBABA), get off at "Lotyšská", and proceed as above.

Taxi

Special transport

Special buses will bring the participants only from the Academy Residence to the Institute every morning. The departure times are given on the notice board at the Registration Desk.

Air and railway transport

Prague has direct air links with most capitals in Europe and with many overseas countries. The international airport Praha is situated about 20 km (12 miles) from the city centre. Of buses connecting the airport with the city, we recommend bus No 179 for reaching the Institute and bus No 119 for connection to the Metro station "Dejvická" (line A). Bus fare: 12,- Kč.

Buses operated by the CEDAZ Co run from the airport to the city terminal, near the Metro station "Náměstí Republiky" (line B) in 30-min intervals. Bus fare: 90 Kč.

International trains leave Prague from the following stations: Praha - hlavní nádraží (Main Station; Metro line C), Praha - Holešovice (Metro line C), and Praha - Smíchov (Metro line B).
