For good-value style
When it opened as House Hotels’ Vault Karakoy, this smart little hotel was one of the pioneers of Istanbul’s new wave of contemporary boutique stays. Now it’s joined Marriott Bonvoy, but thankfully its understatedly stylish bedrooms remain unchanged, with wooden desks in every room, old iron radiators and arched windows overlooking the affluent Karakoy street. It was once a bank built in the 19th-century in Eclectic style, and elements of its original incarnation survived the careful restoration – spot cash registers, a safe-turned-drinks cabinet in the bar, and a wine cellar in the original vault.
