Frankfurt is a city of contrasts. Wealthy bankers, students, and granola drop-outs coexist in a city that has some of the highest, most avant-garde skyscrapers of Europe next to well maintained old buildings. The downtown area, especially Romer square and the museums at the River Main, draw millions of tourists every year. Both business and leisure travellers will find in onhotels.com the best way to visit this dynamic city at affordable prices.
