Do like the Madrileños: visit the El Rastro flea market on Sunday mornings and have a drink and dinner in one of the many tapas bars.
As a food and culture lover, La Latina is the place to be. This district gives you a good impression of what street life used to be like. La Latina was already inside the city wall in the 19th century, making it one of Madrid's oldest districts. The street pattern with large squares and narrow streets dates back to the Middle Ages, but the current buildings mainly date from the 19th century. The district is particularly popular with drink and food lovers. It is teeming with tapas bars and restaurants. New ones are being added all the time. You can have a great time here from morning to night.
