The ultimate dose of happiness and colorful gardens – it all comes together in Madrid’s Retiro Park. Actually, you only have to walk through the entrance of the 1.4 km2 big green space and you immediately feel like you are transferred into the world of charm: the birds are singing, couples are paddling in the boats on the azure blue lake and underneath the linden trees, the violin guy plays Beethoven's fourth symphony. Well, sometimes you just have to appreciate those kitschy moments. By the way, to discover the full park as its best – including the stunning glass palace – rent some City-Bikes and there you go! They make it even more fun to head to the next restaurant place.
