Carlos and his parents were perfect hosts during our month in their clean, safe, well-equipped airbnb in Barrio Santa Cruz, Seville's labyrinthine cobblestone historic center. Tourists, tapas bars and scooters turn Calle Mateos Gago into a civilized party-zone every afternoon and evening, but no crowd noise invades the apartment. Recommended indulgences: Aire Ancient Baths (spa), Mama's Restaurant (on Mateos Gago) and Mercado de Triana (fresh meats, fruits and vegetables). Tip: Buy your tickets to the nearby Real Alcazar and the Cathedral/Giralda Tower in advance online.
