Take the underground line C to Roztyly. From there, you can continue ON FOOT (about 10 minutes). Walk outside the station and uphill, passing on your right the Koliba restaurant. Continue straight ahead, through a parking lot and passing an apartment building on your right, until you reach a grassy area with a children playground to the left, and the yellow building of the International Montessori School of Prague to your right.
If you wish to avoid the steep hill, especially in inclement weather, you can take one stop on the 135 bus line (direction: Chodov) from Roztyly to Dědinova. The WALK FROM THE STOP (5-8 minutes) is much easier in inclement weather! Turning right, cross the parking lot, reaching a strip mall ahead. Follow Krejnická street to the right and turn left into Augustinova; the school is just beyond the apartment building to your right, past the small playground, on your left.
FROM THE CITY: head south on Sokolská, continuing onto 5. Května/Brněnská. Take the exit towards Kutná Hora/Chodov/Spořilov. Keep left at the fork, following the sign for Horní Roztyly, and take a left onto Ryšavého. Take the second right into Augustinova and an immediate left onto Gregorova, which is essentially a parking lot; follow it around the apartment building block, and then take a sharp left into Hrudičkova (in front of the Hotel Globus). The school will be a low yellow building on your right.
FROM THE PRAGUE HIGHWAY CIRCLE (Jižní spojka): take the exit towards Brno/Chodov/Spořilov/E55 & E65, and merge onto 5. Května/Brněnská. From there, please follow the instructions above.
