Caroline was welcoming and thoughtful. As others have mentioned, she's warm, intelligent and aware. Providing a bottle of chilled white wine (and other items) goes a long way toward making weary travellers feel at home! The boat is comfortable and charming. Sitting on the deck as the birds swim up to visit (and the tour boats motor by) provides an experience of Amsterdam you would never get in a hotel. The location is convenient for public transit -- which is excellent in Amsterdam -- but is still quiet at night. We enjoyed it very much.
