The conference will be held at:
Institute of Nuclear Physics Polish Academy of Sciences ( IFJ PAN)
ul. Radzikowskiego 152
31-342 Kraków, Poland
Detailed instructions how to reach the Institute can be found here
UPDATE: Because of the ongoing constructions the direct tram lines connecting the downtown and the institute area have been unfortunately shut down. There is a replacement bus 704 which connects the stop 'Teatr Bagatela' in downtown and the stop 'Bronowice Wiadukt' (about 15' on foot from IFJ). The bus leaves every 3 min and is for free, but the trip takes more time. Depending on the hotel location there may be better connections -- it's best to use online services, e.g. jakdojade.pl or google.
