When visiting Buenos Aires, the most convenient mode of transportation for tourists is the Subte, which is the local metro system. It's user-friendly and covers a wide range of major areas throughout the city. Alternatively, city buses, also known as "colectivos," are a popular option, but it's advisable to familiarize yourself with their routes before using them.

Buenos Aires looks the most beautiful in spring and fall. The weather is mild, and the blooming flowers and golden yellow leaves surround the city with bright colors.

If you're looking for some great places to visit in Buenos Aires, be sure to check out La Boca. This historic district boasts colorful buildings and street tango performances that are sure to entertain. Another must-see is San Telmo, known for its famous antique market.

When watching tango in a club or 'milonga' in Buenos Aires, it's important to dress appropriately and avoid speaking loudly during the performance. If you'd like to participate, it's recommended that you have a basic understanding of tango movements.

Leaving a tip at restaurants is not required, but it is greatly appreciated. Typically, customers give a tip of approximately 10% of the entire bill if they are pleased with the service they received. The change can be left on the table or given directly to the server.
