Private guide for Berlin?

All of the walking tour companies in Berlin have private guides available. Insiders, Original, Brewers. If you look on their websites, and contact them, tell them what you want, for how long, etc. you will get prices.

For very up-to date reviews, I suggest looking on Trip Advisor, the Berlin "Things to Do" page.

Thank you so much. I will pursue both.
