Your budget

It's a wash

Your lifestyle

Depends what you want

Bonn feels like “Six federal ministries, twenty-five UN bodies and Beethoven, in a city of 340,000 twenty minutes upriver from Cologne”, while Frankfurtis “Germany's most international city — the ECB, the airport, and English that actually gets you through the working day”. Climate is a real differentiator: Bonn among germany's mildest — sheltered in the rhine valley below the siebengebirge, winters that rarely freeze hard, and a cherry blossom that now opens in late march. Frankfurtoceanic-continental — mild wet winters and warm summers, among the warmer german cities thanks to the rhine-main basin.
