La Paz, Bolivia
La Paz is not the most beautiful city and it feels a lot poorer than the rest of the continent. In fact at one point, somebody just grabbed me and starting crying telling me that things were so difficult there.... but you know- I had a good time and it's dirt cheap. It has the obligatory main square which is 'ight but it's just an interesting 'looking' city. Every road appears to be at a different altitude and it's surrounded by mountains. Probably won't go back but it's worth a visit.
Insider Tip:Bus tour is a lot more informative than the walking tour. Stay for three days and climb the local mountains.
