One day
Enter the Old City down Souq al-Hamidiyya to the Umayyad Mosque and Saladin's tomb, then walk Straight Street past the Azm Palace to Bab Sharqi and the Roman arch. Spend the afternoon in the Bab Touma lanes among the churches and courtyard houses, ending with mezze in a courtyard and pistachio ice cream from the market.
