Casa del Ratón Pérez

Casa del Ratón Pérez? Don’t be fooled—it’s not a mouse’s home, but Madrid’s most whimsical fairy tale stop! This candy-cane-red-and-white cottage is the official HQ of Spain’s tooth fairy, and that grinning little rodent outside? A must-photograph icon. Step inside and magic unfolds: colorful murals, tiny mailboxes, even money transforms into “tooth gifts.” Whether you’re here with kids or chasing childhood nostalgia, this spot turns an ordinary street into a real-life Alice in Wonderland moment—pure joy in every corner.
