Long-term shared flat in Colombo 7?

Hi guys,

I am brand-new to this website and forum.

I will be in Sri Lanka in July this year to work for an international NGO for at least 2 years, and am looking at different accommodation options in Colombo. I love Colombo 7, and am thinking about a room in a shared flat (with private bathroom), with internet access and cable TV. I am looking for something for about 300USD or so a month. Do you guys think it is possible?

Any help would be appreciated. Thanks!
