Following a soft opening last summer, the 270-room Marti Istanbul Hotel now has completed all public spaces and is fully open for business. The luxury property, in the Turkish city's Taksim district, includes a spacious courtyard between the entrance and street. A street-level restaurant, Brass, features French, Asian and Turkish cuisine, while the mezzanine-level Quad Restaurant & Bar provides a lounge atmosphere with an Ottoman tent motif. The hotel also has a 9,100-square-foot spa and 7,400 square feet of meeting space. A panoramic terrace on the 12th floor opens this spring.
