We had a great time with Kaspar. He met us in the city center rather than at the ship and that was a little confusing for us. We took a taxi in rather than the subway and were late because of rush hour traffic but once we met up we moved right along. Real nice guy, smart, knowledgeable, showed us all around at a pace suited for us, very professional and easy to be around. I wouldn't hesitate to book him and highly recommend him, you won't be disappointed.
