Istanbul-
Spend at least a week here and stay in different places. Taxim is amazing as is Babek. The islands are fun and Sultanamed is very interesting. Take a Turkish Bath! Ride the Ferry! Go to the Grand Bazzar. Sit in a cafe and talk to the locals while you sip tea and play backgammon. It’s beautiful. I’d go back tomorrow.
Bodrum-
Amazing and fun! Go on a boat trip. Visit the castle. There is a yacht club that has music and dancing and right across the way, on the roof of a building is a pizza joint that has pizza that is 2 die 4!
