In fact IS a beach, but the sea is in the opposite place Mathilde and Vova are sitting in. It must be Ostende, one of the most famous Belgium beachs. The city is immediately after the beach. We have a beach like this one in my country, Argentina. It's name is Mar del Plata. If you takes a pic from the sea, looking at the city, the photo will appear qite similar than the one you may see Michael, Mathilde and Vova...You'll see the sand and then, the city buildings.
