A district too broad for one answer
Mean Chey covers several south city environments, from established local streets to new apartments, boreys and major road projects. Treat the name as a starting point. Chak Angre, Stung Mean Chey and Boeung Tumpun have different relationships to the centre, the Bassac and the main roads.
The district has become a major development corridor. Property research identifies vacant land, Hun Sen Boulevard and the route towards Techo International Airport as drivers of new housing and condominium activity. That does not make every part attractive to renters. It means the area is changing at different speeds.
Choosing the right southern pocket
City Bus runs on larger southbound roads, while PassApp and Grab tuk tuks handle the side streets. A motorbike or car helps once the address moves away from established commerce. Test the school and work route, and check how the approach behaves in wet weather. A wide new boulevard may improve movement for drivers while making a crossing harder for pedestrians.
There is no current rent research for Mean Chey in the map record. The housing range is broad, from local homes to newer condos and borey developments. Ask about water, power, drainage, parking, construction and the distance to a daily shop. Do not infer the condition of one southern project from another.
Families and the new south
Mean Chey contains the International School of Phnom Penh campus on Hun Neang Boulevard and the National Institute of Business beside the new Stung Mean Chey Market on Street 217. These are useful anchors for specific households, not proof that the whole district is school walkable.
Would I live here?
Yes, but only after choosing the sub area. Mean Chey is promising for newer housing and southbound routines, yet too broad for a generic recommendation. I would compare an established street with a new development, then let the daily route decide.
