We produced our paper voucher ticket to the attendant and she printed us the strip ticket. She directed us upstairs to the upper deck, but without giving us the brochure and headphones. Luckily, we had earphones we had from previous country's tours that we did . We then realised it was the Express Tour first that we did when we got on from Romer. When the tour completed back at Romer, the next Skyline Tour was due to start in 30 minutes. We walked around and got on later. It was a comprehensive tour, covering the opposite sides of the Express Tour. Enjoyed it.

Bus Ride Only Highly recommended , very informative, worth every cent, the bus driver was hands-on and ver helpful. Flix bus arrived one and a half hours later, thereby Reducing substancially our visiting time to the various destinations offered - Hop on Hop Off, in fact we could not....Thank You!!!!!

Great experience, you can use it as a taxi in frankfurt to jump from one area to another, the ticket is valid for 24 hours which is great and you can hop in and hop off as long as you want and I would suggest to pay the 3 euro extra to get the other line as well.

Thoroughly enjoyed both tours and took advantage of the hop on hop off to explore Christmas Markets and historical sites. Definitely recommend.

the app didn’t help knowing the bus timing. However it helped finding the nearest stop.
