I stayed one night at the Radisson Blu Hotel, Istanbul Sultanahmet, and it was a truly wonderful experience. From the moment I arrived, I was welcomed with warm and professional service, especially by Mr. Hikmet at the reception — he was extremely kind and helpful. The room was very clean, well-maintained, and comfortable, with all the amenities I needed. The breakfast buffet was rich, varied, and delicious. The location of the hotel is perfect, right in the heart of the historical area, within walking distance to the Blue Mosque, Hagia Sophia, and other major attractions. I will definitely choose this hotel again on my future visits to Istanbul. Many thanks to the management and all the staff!
