This was an excellent tour that matched my expectations/requests exactly! I had an eight-hour layover in Madrid and hired Tours By Locals to show me around. Mayte met me on time, guided me through some of Madrid's most iconic neighborhoods, gave me a really wonderful tour of Prado highlights, and took me to a terrific tapas restaurant. She then accompanied me back to the airport with plenty of time to check in. P.S. I saved a lot of money by taking public transportation instead of hiring a driver!ou
