The Czech-Catalan Conference in Mathematics will take place in the newly reconstructed building of the School of Computer Science of Faculty of Mathematics and Physics, Charles University, which is located in the very historical Prague's quarter Mala Strana, just below the Prague Castle (see the photo).

Participation at the conference including the Friday banquet is free for registered members of the Czech and Catalan Mathematical Societies. For other participants the banquet ticket costs 1500 CZK (around 45 EUR).

The accommodation can be reserved in guest rooms in student residences upon request. (A limited pool of rooms reserved for the period May 27-29, will be offered in first come, first serve basis.) Sorry, we have run out of the reserved pool.

Besides individual arrangements, the two following hotels provide accomodation for the event:

• The taxi and minivan instructions as above.
  Minivan costs 960 CZK for 1-8 persons. The estimated cab price is 650 CZK.
• From the airport by public transport:
  1. Take bus no 119 from airport to Dejvicka (final stop),
  2. then subway A (green line) to the final station Skalka
  3. and then behind corner take bus no 271 or 154 and go 4 stops to Nadrazi Hostivar.
  Then the big building of the hotel is easily visible.
  You can buy an 1 hour ticket on the machine at the airport at a price of 12 CZK. You should mark it as you enter the bus, it is valid for one hour.

Between hotels and the conference site
is easy by public transport since all lie at tram no 22 line.
