To make the most of your day, consider walking or using public transportation to move from one location to another. Taxis are also available, although they can be more costly and prone to traffic. A one-way public transportation ticket costs € 1.40 and a taxi ride from the airport to the city center costs around € 25.00.
If you have more time, consider adding a visit to the Metropol Parasol, an incredible wooden structure with rooftop views. If you have less time, skip the Plaza de Espana and spend more time at the Real Alcazar. Don't forget to wear comfortable shoes and stay hydrated!
