Istanbul, the noisy metropolis on the Bosporus Strait lauded by many a travel ranking, has much more to offer than grand mosques and bazaars. Away from the din of typical tourist haunts, a walk around the neighborhoods of Karakoy, Balat and Kuzguncuk will peel back the surface to reveal the city’s multilayered history, and the lifestyles of those who’ve lived it. The Istanbul neighborhood of Karakoy, an up-and-coming area hemming the Bosporus Strait, includes this sun-splashed sidewalk cafe, a small church and, throughout, boutiques and galleries.
