Bohemian, colourful neighbourhood that used to welcome immigrants from Europe in huge numbers. Walk around and enjoy European cuisines here.
When visiting, try to keep to the areas that have been developed for tourists. The rest of the neighborhood is poor and often the scene of small crimes. Taking the bus or taxi to get there is a good idea.
