From personal experience, I’d say renting a car just to get around Madrid isn’t the best idea. Parking in the city center is a real headache. As for the airport, the short-term parking lots near the terminals are expensive, but the long-term lot, Larga Estancia, has much lower rates and free shuttles to the terminals. If you arrive late, the 24-hour Express Airport Bus is the best way to get to Plaza de Cibeles. I recommend checking out https://madrid-mad-international-airport.com/ before your flight, as it has complete information on 24-hour bus routes and current parking options. It’s an independent travel guide that we stumbled upon by chance, but it was very helpful to us. Have you booked a place to stay near the city center yet, or are you still looking?

Pour un court séjour à Madrid, comparer le coût total d’une voiture de location avec les transports publics peut aider à choisir l’option la plus pratique. Il faut aussi tenir compte du stationnement, de la circulation et de la distance entre l’aéroport et les lieux prévus. Plus d’informations : https://spinsonly.fr/.
