The following is selected short local information for Prague. You can find more info e.g. on Wikitravel.
In the Czech republic, we use Czech crowns (CZK, Kč). Due to continuous interventions of the Czech National Bank, you get approx. 27 Czech crowns for 1 euro, which should make your visit pleasantly cheap.
To get to Malostranské náměstí (Venue of the Training School), the best option is to take bus #119 from the airport to its terminal stop Nádraží Veleslavín. From there, you can either take tram #20 that goes directly to Malostranské náměstí, or – which may be a little faster – you can take metro to station Malostranská and from there tram #12, #15, #20, or #22 to Malostranské náměstí (one stop).
Prague has a well developed and reliable public transport, with the following prices for tickets, which are valid on buses, metro, and trams (more details here):
You can buy tickets in slot machines in the underground stations, in most newsstands, specialized public transport shops, Prague transport information centers at the airport and the main railway station. You can change between the buses, metro, and tram for no additional charge as long as your ticket has not expired. Remember to validate your ticket as soon as you get on the bus/tram or in a metro lobby by sticking it into a yellow machine with a green glowing arrow, or you may be subject to a fine of 800 CZK if you are caught. Each type of ticket should be validated only once – the first time you start to use it (never when you change).
