Location Context
Sothearos Boulevard is one of Phnom Penh’s main roads, running along the western side of the Bassac River. It links key parts of the city, including areas near the Royal Palace in the north and connections towards National Highway 1 in the south. From here, most central destinations are either a short drive or an easy ride away.
Tonle Bassac is a riverside sangkat in Chamkarmon district. Over the past decade, it has shifted from being a quieter neighborhood into one of the city’s more active development zones. The riverside setting gives the area a mix of city convenience and open river views, along with better access to new roads and infrastructure.
