Communication with Kamil was good. I got a bit lost looking for the hotel and Kamil was on the phone to help. The hotels name is Sultan's Inn. I loved it. The concierge was very helpful and welcoming. My room, including bathroom, was clean. The morning breakfast buffet was great. Wifi was adequate. A/c works. I can find no fault. A great place to rest up before spending a day exploring Istanbul. I stayed 5 nights.
Location is in the tourist area, near the Blue Mosque. Very close to the "Little Aya Sofia" which must be visited.
