The fourth project from Istanbul's House Hotel group is new accommodation inside the former Ottoman Bank buildings in the up-and-coming neighbourhood of Karaköy. Dating from 1863, the storied structure, restored by Turkish architect Han Tümertekin, retains all of its original details, while the contemporary décor was created by Sinan Kafadar - best known for the interiors of both Four Seasons hotels in the city. Artwork comes from owner Yilmaz Ulusoy's personal collection, while advisor Zeynep Berik also commissioned emerging local artists to create exclusive pieces for the hotel. High ceilings further create a rich library atmosphere, complete with antiques and vintage objects and further down the lobby, the old vault serves as a backdrop to a sophisticated bar area.
