We did this private tour with Karin Schneider. She is a fantastic guide and a wonderful person. She made our trip to Berlin and the surrounding area so special. It was raining and she went out of her way to bring extra umbrellas and rain gear for us. She knew we were from abroad and may not have all the appropriate rain gear. She not only showed us Potsdam, but went out of her way to show us the historical attractions in the surrounding area. We have a young child and she made sure to tailor the tour to his needs and stamina. She even brought us pastries so we could try local fare and made sure we were comfortable. We could not have asked for more in a guide. Our only regret was that we didn't stay in Berlin longer to do more tours with her. We can't wait to make another trip to Berlin and have her show us other sites and attractions.
