Last October I went to Istanbul. I had been dying to go for ages but couldn't find any friend interested, and travelling solo was too daunting. So I found these women that organize tours of Istanbul for women only and had the time of my life. The guide was excellent and the support woman knew absolutely every single place. We had a great time all eight of us in the group. We saw amazing sites, and in the evening we visited great restaurants and bars, so stylish and incredibly affordable, and made friends with the locals. I recommend going to the hamam in Cemberlitas, that was an unforgettable experience, especially after a long day touring... I'll definitely be going back!
