do on your own if you dare. you will be hassled to death and so confused you will want to flee. I would only shop here with a Turkish friend.
Hagia Sofia Rating: Not Rated
Impossibly long lines and almost an hour wait no matter how you plan to see this. A great deal of walking!!! Guide needed to make what you are seeing meaningful but ship horribly overpriced and there are great guides on the internet...check trip advisor.
Taxi drivers will rip you off up and down with every trick in the book. they are merciless. Do not get in a cab.
