Fides is a perfectly decent hotel, but little things, like different colored light bulbs (ie. some warm yellow, some harsh white) in the overhead light in the room, front desk staff who were hit-or-miss (the tall gentleman did not seem interested in helping me beyond the basics of his job description), and the fact that when I inquired about making a local call from my room, he said it would be "very expensive." (The next hotel I stayed at in Istanbul charged me nothing for local calls.) Otherwise it is a 10 minute walk to the sights of the Blue Mosque and Hippodrome, so if you don't mind roughing it a bit (by Western standards, of course), Fides is your place. Also, Fides caters to more conservative types, so don't expect to bring anyone back to your room, as it will be considered "indecent." (My next hotel didn't care.)
