Street 21 runs parallel and between Norodom Bvld and Sotheros Bvld. It is a long quiet street. We are close to Street 830, and 2 mins from The Lost Room . We are behind Wat Svay Popaye If you come to what looks like the end of the road, turn right and left street 21 continues....... Gates open 15 minutes before scheduled class starts. Bring the instructions with you. Do not expect your driver to know where we are. For tourists and new folk to Phnom Penh: HOUSE NUMBERS ARE NOT SEQUENTIAL some times there are two or more House numbers the same in one street! Parking for Bicycles & Motos only inside. Cars please park on Street 21 - sorry. Som Orkun!
