On a recent trip to Europe my husband & I and another couple found ourselves with a very short layover in Amsterdam. Since we had five hours before our scheduled return flight we decided to hire a private guide. Frank met us at our ship and took us on a tour of the city which included a walking portion, a visit to Anne Frank's house, as well as a canal cruise. We all felt Frank was exceptional. He is very knowledgeable and professional and he took care of all our needs. We highly recommend him.
