Great location - the guesthouse is walking distance from Blue mosque, Hagia Sofia, Cistern Basilica, Topkapi palace and metro station. It was really convenient to visit places and then come back to rest for a while. Staff was very helpful in suggesting places for specific things we wanted to shop for and with all the general information that we requested. Breakfast was amazing and got our day started really well. The room was clean. It would be nice to add tea/coffee facilities in the room though.
