#17 – Singapore – Singapore
The city of Singapore is probably one of the cleanliest cities in the world. Besides being one of the cleanliest cities in the world, it is also one of the most expensive cities in the world. Not to mention that this city is extraordinarily beautiful.
If you have a pocket deep enough for a city expensive as Singapore, visit the city’s shopping district Orchid Road. When you get tired of shopping in this cosmopolitan city, you can always visit its Jurong Bird Park.
