Why Istanbul for a city break?
Istanbul is one of the world's truly great cities — the only metropolis that spans two continents, a city of 15 million people built on the ruins of Byzantium and Constantinople, where Byzantine mosaics and Ottoman minarets share the same skyline and the Bosphorus connects the Black Sea to the Mediterranean. The Hagia Sophia, built in 537 AD, is one of the most extraordinary buildings ever constructed. The Grand Bazaar has been trading continuously since 1461. The food — meze, kebabs, börek, baklava, balık ekmek (fish sandwiches) on the Galata Bridge — is extraordinary.
From London it's under four hours; well served from most UK regional airports with direct flights. The Turkish lira's significant weakness against sterling has made Istanbul one of the best-value major city breaks available to UK travellers — a Michelin-quality dinner costs what a mid-range restaurant would in London. April to May and September to October are the ideal months: warm, dry and free of the intense summer heat that makes July and August oppressive. A long weekend is the minimum; four or five days does the city real justice.
