Quick tips when choosing:

• If you prioritise quiet, green streets and top international schools — Cinnamon Gardens or Narahenpita.
• If you want nightlife, shopping and high-rise living — Kollupitiya or Bambalapitiya.
• For best value with reasonable access to the city — Wellawatte, Borella, Rajagiriya.
• Check commute times for your workplace (Colombo traffic can add a lot to daily travel).
• If buying, research flood risk and building management (important for older buildings).
