''I cannot imagine a better tour than the one Dr. Almudena Cros provides. She has been invaluable to me in my research on Ernest Hemingway's participation in the Spanish Civil War, and we are currently collaborating on a documentary with Villon Films. She knows the war, she knows Madrid, she knows art history, and she is passionate about all three. She is a born teacher, full of enthusiasm for sharing what she has learned while continuing to learn, qualities that make her a perfect guide to Madrid, Jarama, Brihuega, or wherever else in Spain you might want to explore. Across Madrid is not just a job or career for Almudena; it's her calling.''
