I would suggest that you take a look at Cebu instead of Manila. The expat community is tighter here, the city is much less crowded and there is more of what you would expect in terms of Pacific Island living going on in this part of the Philippines. All that being said, Cebu is becoming a prosperous and sophisticated Industrial / Commercial city as well. You might find that it is the right recipe for the Philippines.

If you (or anyone else) would like to discuss Cebu with me, let me know. I am a British expat and I run a real-estate business here. I can help find nice rental property, or just point you in the right direction if you just need some tips or whatever.
