Kamil greeted us upon our arrival, showed us to our room, and answered all of our questions. We had a beautiful room (note: it is two twins pushed together, but we had no issue with that) with plenty of space and even a teensy balcony with a view of the water. Kamil also provided us with a large bottle of water in the fridge (Istanbul water is debatably potable, and certainly not palatable due to the extreme chlorination) and said that we were welcome to the packaged snacks in the fridge.
We felt that the listing was very accurate. The room was comfortable and perfectly suited our needs. The free breakfast (8-10 am) was a wonderful way to start the day, and there was a great view out the window (also from the deck, but since mornings were often chilly we stayed inside). Our room was always clean when we returned at the end of the day, one of the benefits of staying in a hotel. The location of the hotel allowed us to run along the waterfront in the mornings, and at night we were able to enjoy a cup of tea on the roof deck as we checked our email.
The neighborhood of the hotel is definitely touristy, as it is in Sultanahmet. There are a lot of restaurants on the nearby streets and every one will have an employee trying to get you to eat there. That said, a lot of the food looked great. We tended to eat our meals as we walked rather than sat down so that we could cover more ground. The hotel was a short walk from the square (Hippodrome, Blue Mosque, obelisk, Sultanahmet tram station, etc) and we loved strolling home at night.
Bonus: on Wednesdays (at least in the afternoon), there is a farmer's market at the end of Gelinik Street (where it crosses the main street winding down from the square). We loaded up on delicious, fresh fruit to snack on throughout our trip.
