By default, the organizers do not provide accommodation during the conference, as there are numerous hotels all around the city. We refer to the Prague Information Services website (maintained by the city administration), or any other standard choice, such as this one. The conference is held at Prague's Lesser Town (Prague 1, western bank of the river). We recommend to book early, since the main tourist season in Prague usually starts by the end of June.
For participants who seek for a budget option, we recommend to book student dormitories of the Charles University. The list of dormitories can be found here. The nearist options are "kolej Komenskeho" (map), "kolej Kajetanka" (map), and "kolej Petrska" (map). All dormitories are about 20-30 minutes walk, or a short ride by public transportation, from the conference venue. The price list is here. To book a dormitory, send a request to firstname.lastname@example.org (do not use their website, it does not work well).
