I took a walking tour through the Luxembourg tourism office. Our tour guide, Milda, was a lively young woman from Lithuania. She did reflect Luxembourg City, though, as there are more than 150 nationalities represented in this tiny country. Although we'd walked some of the spots of the tour prior to, listening to the stories behind the landmarks made it much more worth it. You can book a tour at the Luxembourg tourism office for 10 euros. A walking tour is a great way to get acquainted with the city, especially if you have just two days in Luxembourg City.
