Toledo is known as the city of three cultures thanks to the history of Muslim, Jewish, and Christian coexistence (and rivalry). The churches, synagogues, and Mudejar architecture are gorgeous and the city is very well cared for. It is larger than Ávila with more to see and do, very hilly, and very walkable. The Spanish painter El Greco lived here and his pieces pepper the churches and museums. If you're a fan of his this is a great city to visit.
