We had a wonderful time staying at this hotel. Azamat and all the staff at Blue Tuana were incredibly accommodating and friendly. Check-in was easy and the location is perfect, within walking distance to tons of cafes, shopping, sites but still tucked away from the main streets in a quieter part. We had a small issue with our room but Azamat was super nice and took care of us. 5 stars all the way. We really enjoyed our stay in Istanbul.
