Can't say enough good things about Onur's Sublime Porte Hotel and our host on site Emrah!
Room
We had the terrace room which had excellent views of the Bhosphorus and the room was nicely appointed and clean.
Location
Best location in Sultanahmet and central to good food and walking distance to all the major destinations. We basically walked everywhere and even made multiple trips a day to Aya Sophia and Blue Mosque square for food and to hang out. Tons of restaurants a stones throw away. Metro and the tram stations are also near by.
Event Reservation and transportation
Emrah helped us get reservations to a Bhosphorus boat dinner and live show at a very reasonable price, which I recommend doing as I probably wouldn't have thought of it. We were also able to get airport transfers at a super competitive rate!
Emrah really made our stay excellent and his knowledge of Istanbul is second to none. He is extremely professional and proficient at English.
I would definitely recommend staying at the Sublime Porte, it's a total package!
