Leave the big roundabout in the Vítězné náměstí (Victory Circus) for Jugoslávských partyzánů Street (there is a BILLA supermarket in this street). Take the first right and drive along the Rooseveltova Street past the big building of Zeměpisný ústav (Geographical Institute) all the way to the corner of Rooseveltova / U zeměpisného ústavu streets. We are on the right side in the corner house number 12. Ring our bell beside the gate.
