How much should a private guide for Topkapi Palace in Istanbul cost?

One traveler asks what a fair price would be for a 5-hour tour with a good guide, questioning whether the going rate is really overpriced.

A traveler who visited Topkapi Palace a second time says she wouldn't go again or recommend it to friends, and advises considering other options before booking a tour there.

According to one traveler, paying about 4000 lira for just a 2-hour visit to Topkapi Palace is unreasonably expensive, even though she loves the place. She suggests hiring a good guide for a 3-hour tour and then spending extra time exploring the palace on your own.
