I have stayed here for spending 6 hours transit at the Colombo airport with my 4 year old boy.
The Hotel itself is very nice and very very large for my boy to play around. Nice bed to relax. But the aricon is not cool, feels very hot after shower. The bathroom has nice bath tub for my boy to play and has all the essentials.
I fell the price is little expensive 55USD for 6 hours but because of little airport and nothing to go around, you have no choice. They give wake up call 1 hour before your flight so no need to worry of delay.
