I think this was recently on TV here in Spain - is it in Bali?
When I stayed in Sumatra I was paying $3 a night, so this is a bit out of my league. $500 a night seems a little excessive if you ask me, which you did!
There are many great places to stay at a fraction of the cost where you can still get the 5-star treatment for much less. Still, each to their own suppose. If no-one would pay, I suppose they would not have built it!
