I cannot recommend this hotel highly enough. I had a wonderful five nights here, where I was made to feel at home.
The rooms are what could be called Ottoman minimalist in design and very comfortable. There is a lovely rooftop terrace, with great views of the Blue Mosque and Aya Sofya, both of which are only a short walk away. Downstairs there are two lounge rooms with fires, which were greatly appreciated during my chilly mid-January stay.
The hotel is also only a short walk away from the Sultanahmet tram stop, which makes it very easy to reach other areas in the city, especially Eminönu/Galata Bridge (for the Spice Bazaar and ferries) and Karaköy (excellent for food and nightlife).
Finally, the staff are exceptional. All of them were incredibly friendly and accommodating to requests. They gave me lots of suggestions on things to do and places to go, helped me plan itineraries and booked restaurants, hammams etc. for me.
