Renting for 6 months in Colombo or Negombo

My husband and I will retire in Protected content . We are thinking about renting for Protected content every year in either Colombo or Negombo. I lived in Chennai and have been to India many times, but never to Sri Lanka.
We plan to arrive October Protected content would love to talk to expats there. I speak a little Tamil.
Thanks,
