The hotel is located a stones throw away from Sultan Ahmet Mosque, Haga Sopiha and Topkapi Palace. If you are in IST for a few days this would be a place to stay as it is very reasonable, the staff is very courteous and there is a ton of tourist spots within 10 mins walk. There is a tram station next to Sultan Ahmet that will connect you to the entire city.
Also, I would recommend that you use the taxi service as it was 20 Euro (USD 23) each way but the transport vehicles were huge and it had ample space for your luggage and for you to sit comfortably.
Finally, this is not a 5 star hotel but for the price its steal of a deal due to the closeness to tourist areas and hospitable staff...
