The Retiro barrio
The Retiro barrio nearby hosts the main train station in the city. As you would expect, the place is packed with commuters and travelers any time you go there. There is also a great lifestyle scene here, with high class restaurants, boutique shopping, and clubs. It is home to a wide variety of immigrants. The whole area and its business is quite dizzying, especially for a first time visitor or if you have never lived in a big city so remember to take breaks and give yourself regular sit-downs. Thankfully, there are plenty of cafes and restaurants that are little drops of calm in the bustle of the town.
