I went on a Sunday, on a really really freezing cold day (-2 degrees). I didn't expect so many people! It was a little crowded but everyone gets a seat so I was not too worried. It was too cold to go on the top deck, however it was still lovely. Frankfurt is a beautiful city, it's definitely worth spending a little time on the river. I was equally amazed by the staff, just two people serving drinks and food but they do it so efficiently and so quickly! (I suppose that is Germany for you! ;)

The Frankfurt Card is extremely recommended for all travelers who visit to Frankfurt. You can use it for city-train, tram, and city-bus. The best choice to enjoy the city with one single card. You may exchange and validate the card at the Tourist Information which might be available at Central Station (Haupbahnhof).

Mitali was our guide. She took us to the Kleinmakthalle, the Red Light District, to some areas with officially sanctioned Graffiti, the Gallery Department Store 7th floor lookout point and through some neighborhoods we would otherwise not have seen.

The tour was amazing. The guide was very helpful and fun, he is a good man who loves his job. Sunday is the best day to go because then you can speed around the city while everyone stares at you flying by.

Absolutely worth while. We were in Frankfurt for 2 days and bought the card to mainly move around freely. It also proven to be of a very good values in other instituyions like meseums.
