Some of the things I like about Singapore are slowly getting less good due to the 70% increase in population over the last 10 years, but here goes:
Airport
Easy access to cheap eats.
Public transport access and low fares.
Range of cars used as taxis (but not the taxi fares themselves)
Well planned housing, overhead sheltors for the rain.
Central location to rest of Asia.
Generally peaceful intergration between Chinese, Malay and Indians and their religion.
Cheap cars (ok, I jest!

)
