Great little hotel with an excellent restaurant in the courtyard. Room was clean and had all the basic amenities: wifi, safe, shower stuff, etc.
Staff was very helpful, there's always someone at the front who can help you whether you need directions, recommendations, or anything for your room (such as an outlet converter).
They also arranged our PCR test (it was a requirement for our flight back), with a medical professional coming to the hotel to do the test one day before our flight.
The hotel is in the middle of Sultanahmet, walking distance from the light rail station as well as Blue Mosque, Hagia Sophia, and Little Hagia Sophia. The last one is literally down the street. This is important because traffic in Istanbul can be quite bad so don't count on cabs that much. Streets around the hotel are old and cute, definitely feels like you're in a city with ancient history.
The hotel has a decent buffet breakfast. With the pandemic everyone had to wear masks around food.
