Offering state-of-the-art spacious rooms, the Stay Nisantasi Boulevard which opened in January 2023 has a worthy place at the top of our list. As the first hotel group in Turkey to be awarded a carbon-neutral status, a stay here is a guilt free experience. Bedecked with a modern art collection, there’s plenty to see in the hotel itself. And that’s before we get to the spa - a sanctuary in busy Istanbul offering a traditional Turkish Hammam as well as massages and aromatherapy.
