The hotel locates at the centre of Sultanahmet; it is close enough to walk to many tourist places such as Hagia Sophia, Galata tower, Egyptian bazaar and Tokapi palace. It is also close to the tram station and metro station. However, bare in mind that if you travel by normal airport bus (IST20), you have to walk for a while to reach the hotel.
The cleanliness and staff of the hotel is very nice. Its breakfast is good although there should be more variety of food to choose. One thing that I think need to improve is the water system. Hot water in the hotel is not really hot, and water pressure is quite slow. It might not be a problem if you travel in Summer, but in Winter you might feel water is not enough warm. Moreover, the sink does not have warm water, so in the morning it can be very cold to wash face at the sink.
Overall, nevertheless, it is a pretty lovely hotel to stay.
