Our tour guide, Kevin, was wonderful at answering questions and keeping things interesting for two history buffs in our group, as well as making things fun and light with pop culture references for the third (non-history buff) person in our group. He clearly had experience showing people around and was able to get us into some small shops to see some very unique things up close and personal (for example, the exact spot in which he stood for being measured for custom clothing). We saw some iconic shopping areas that were frequented and his favorite cigar bar and smoking chair. Kevin even met us at our hotel and gave us tips on how to use the tube. This tour was eye catching and memorable, and Kevin was the cherry on top. Admittedly, the non-history buff in the group is who is writing this review. I wasn't sure it'd be may favorite of our two-week trip around Europe, but it sure was the winner. Book this tour! Our group decided we'd like to do the underground city tour next time around.
