The city of Cologne in Germany is a vibrant city with a lot to offer. Visit Cologne's old town with famous sights such as the Cathedral, the Ludwig pop art museum and the Alter Markt. Explore the trendy Belgisches Viertel, where students, fashionistas and cool restaurants set the tone. Shop in Ehrenstraße for both well-known shops and unique fashion boutiques. From there, head to the up-and-coming Ehrenfeld district, known for its multicultural atmosphere, pop-up shops, coffee bars and graffiti artwork. We stayed at Boutique Hotel Maison Marsil.
