Okay but I would not recommend. I'm not sure what all the previous reviews were raving about. Breakfast was decent but nothing special.
1st room smelled of smoke. 2nd room at the back of the hotel was narrow compared to the pictures. In the morning there was loud construction right behind the hotel. We were moved to a front room which looked like listing pictures and was quiet (building in front also had construction but was quieter).
Communication with host was good.
Location is right by Hagia Sophia and Sultanahmet Square which is great and what we were looking for. However, nothing to the fault of the hotel, but the whole neighbourhood is a bit of a tourist trap. Every time you leave the hotel you have to run a gauntlet of people constantly inviting you to eat at their restaurant. I would recommend to people visiting Istanbul for the first time to stay near Galanta Tower instead, and then take public transit (which is excellent in Istanbul) to visit this area for the day.
