Also exploring
Lisbon
Portugal
A sun-drenched Atlantic capital where tram lines weave through hilltop neighbourhoods and prices stay genuinely affordable by Western European standards.
Barcelona
Spain
A Mediterranean city that runs on architecture, food markets, and beach culture — with a tourism problem that makes timing absolutely critical.
Santorini
Greece
The caldera sunsets and white-washed cliffside villages are real — but so is a tourism infrastructure that was never designed for 3 million annual visitors.
Worth knowing
