I give back the car and fly to Istanbul.
Move into a hotel in a quiet neighborhood with colorful houses. It rains. I'm not very impressed my the Blue mosque after Iran. And it annoys me how much plastic bags they waste here. Take a look at the column that they brought here from Plateia in Greece. The same minimalist style as on the battlefield there.
Basilika cistern and Çemberlitas hamam are suitable indoor attractions.
