This is an incredible bookstore that has been a part of Madrid's literary history since 1898. As the oldest bookstore in Spain, it has maintained its original location and has become a treasure trove for book lovers. The store's specialization in mountain, travel, and adventure is unparalleled, offering a vast selection of books, maps, magazines, videos, and materials that cater to enthusiasts of the great outdoors. The staff's exceptional treatment and personal online sales make customers feel valued and appreciated. However, the store's hours could be more customer-friendly, as it is closed on Sundays. Overall, it's a must-visit destination for anyone who loves reading, exploration, and adventure.
