We stayed at the St Regis Istanbul for five nights on a leisure trip to Turkey. We couldn't have asked for a nicer place to stay. The facility was new (built about five years ago), and every surface was as clean as it visibly could be, and excellent protocols were in place for COVID-19 safety. The staff were friendly and helpful from the very beginning to the end, and many of them were good at English and could help us navigate our stay in Turkey. It was easy to plan our activities as well as our COVID test which was needed for departure. The head butler, Bora, was also helpful, courteous, and speedy delivering us a complimentary bottle of Turkish Sauvignon blanc, extra water, as well as other necessary items. We stayed in the Caroline Astor suite which had a beautiful balcony from which we could observe the lively scene on the street below. I would recommend this hotel to anyone travelling to Istanbul looking for am upscale hotel experience, and I would definitely return to this property again.
