I recently had an international business trip that was going to require a layover in either london, amsterdam or frankfurt. After happening upon all of the great TripAdvisor reviews of the Frankfurt on Foot Walking Tour, I decided I'd schedule the 10-hour layover in Frankfurt and take the opportunity to spend 4-5 hours in a city I'm not sure my husband and I would otherwise have a chance to visit. I'm SO glad we did. Although I'm a seasoned traveller, I'm don't think we would have thought to leave the airport in the middle of international travel, but FOF made it very easy - providing us with detailed info about everything from currency exchange, expected weather conditions and train tickets to storage lockers at the airport. Just as promised, Hondo was waiting for us at the airport at the agreed-upon Meeting Point (we were late getting there and were very relieved to see/learn that he's very accustomed to waiting however long it takes for travelers to find their way to meet him). We then hopped the train into the city and proceeded to have a thoroughly pleasant afternoon/evening with just the right amount of information, historical perspective, and exercise - all of which was a particularly welcome/refreshing experience in between middle of two 8-12 hour flights! We really enjoyed the easy company and customized guidance that Hondo provided, and loved getting what seemed like an authentic taste of Frankfurt, its food, and its history. Would highly recommend this walking tour to anyone - it's well worth the relatively low price for peace of mind and a great customized experience!!
