Phnom Penh. Cambodians are extremely freindly and helpful. My estimate is that 90% of them live in what we would call an impovershed condition. The city is both beautiful and horrifyingly dirty. The apartment building below was right beside our hotel. Bars in the windows instead of glass (too hot) and the sidewalks assumed the role of sewers and places to leave ALL your garbage. The smell was 3-dimensional.
These houses are a 10 minute walk from downtown.
