We had an excellent day walking around the city of Hamburg with Marlis. We found out a lot about the history and architecture of the city. Marlis was extremely knowledgeable and engaging. My son found it very helpful with his German language studies. Marlis was kind enough to let him practice his conversational German. Having spent the day with Marlis we had learned a great deal and had some tips for what to do for the rest of our trip including a walk around thew lake and a visit to the Miniatur Wunderland. The Hamburg Greeter scheme is an excellent idea and Marlis was an excellent greeter. Thank you!
