From Sultanhamet Square to Beyazit
The city is far easier to walk than I'd feared, and public transportation is cheap, quick and efficient (if crowded). Most importantly, most of the major sights are packed closely together in or near the historic center. On one of our first days, we walked along the tram line from Sultanhamet Square (next to the Blue Mosque and the Hagia Sophia) to Beyazit: a short, straight walk during which we saw one historic treasure after the other.
