Hi MattHar,
AIM is located in arguably the priciest district on the whole of the Philippines (Ayala Center, Makati City). That comes with advantages as well, of course. You're located within walking distance of almost all the offices of multi-nationals, and this is the financial heart of the Philippines. Disadvantage is that it's a good deal more expensive than the rest of the Philippines. That said, depending on your point-of-reference, it's not too expensive. Indicative figures below.
US$ - Philippine Peso Rate is $1.00 - 46.00
A meal bought at street food stations, where you eat standing, street-side is about Pesos 40-70.
A Mcdonald's Quarter Pounder meal is P130.00
A bottle of Coca Cola is P12.00
A decent, cheap enough sit-down restaurant in this area is about P150.00 - 250.00
A starbucks Latte is around P130.00
A kilo of rice, uncooked is P50.00, a cup of rice, cooked is around P10.00
Price of a movie at the closes cinema is P170.00
Rental where I live (brand new building, high end), P60,000 minimum for a 1BR unit.
Rental at smaller, older places about P30,000.00 - 50,000.00, walking distance from AIM.
Room boarding rate at house located in a village, 15 mins walk from AIM around P15,000 - 25,000. You may be able to get some for P10,000 if you're lucky.
Room rate at a place, 1 or 2 rides away, P12,000 - 30,000.00
Hope these help.
