Oslo is blessed with some incredibly beautiful parks which manage, in typical Norwegian style, to straddle the line between a bucolic naturalness and well-kept grace. As soon as the sun is out this is where you'll find locals lolling, picnicking and often getting their gear off and catching some rays.
Barcelona is an enchanting seaside city with boundless culture, fabled architecture and a world-class drinking and dining scene. Barcelona's architectural treasures span 2000-plus years. Towering temple columns, ancient city walls and subterranean stone corridors provide a window into Roman-era Barcino. Fast forward a thousand years or so to the Middle Ages by taking a stroll through the shadowy lanes of the Gothic quarter, past tranquil plazas and soaring 14th-century cathedrals.
Garden islands and lagoon aquaculture yield speciality produce and seafood you won’t find elsewhere – all highlighted in inventive Venetian cuisine, with tantalising traces of ancient spice routes.

Berlin is like an endlessly fascinating 3D textbook where the past is very much present wherever you go.
