I recently spent part of a week in Bogota. Originally looked into staying in the Candelaria neighborhood, but was told by locals that it is too dicey at night and there are safer areas. Loved spending most of a day there - especially visiting the Botero museum. Then looked into popular Zona Rosa, but eventually settled upon Usaquen. Dont think I could have made a better choice. If you are not into the nightclub scene and like a nice neighborhood with some very interesting architecture and a variety of good restaurants, you will like this. Frankly I was disappointed when I visited Zona Rosa and had lunch in the Zona T section. It is all very nice, but if you live in a big city in the U.S. you will find a lot of the look and most of the shopping just like you have at home. Usaquen, near Hacienda Santa Barbara, was walkable, interesting and safe.
