How come Colombo Hotels are very expensive ?

Try Hotel Renuka or Global Towers in Colombo 04. They are a lot cheaper. The 5 star hotels have a minimum rate in Colombo so they can't reduce. But Global Towers may be on your budget. Plus it has good transport connections.

Hi Why not visit the south of Sri Lanka
Have a Grand old colonial villa set in a tropical garden
with swimming pool renting for excellent rate 
Lovely team at villa to take care of you and your guests
Pleased to forward details
Regards George

Thanks Sammoon, global tower sounds interesting.....
Is this just like a business hotel

Hi george, i don't have any idea on southern part.
Refer me few place

Both business and tourist people stay at Global Towers Residence. And it has some quirky restaurants around the area for real Sri Lankan food: Beach Wadiya where Queen Elizabeth has dined at on the beach! Lovely club called Kinross Club (you do have to get membership) where you can sit by the ocean. THere is a writer's club that meets around there too. Different to Colombo 3, 4, 5 area.

Thanks Sammoon,

Will definitely explore this time
