I was there for two weeks in the begining of July 2013. Location is fantastic, a stone throw from SultanAhmet and AyaSophia and many restaurants. DoyDoy is a local good option (better than Buhara 93, where I found hair in my food twice).
Mr Mehmet is a dedicated host who really cares about the hotel and guests.
Only issue you might find is that rooms are quite small, but decoration, service, cleanliness and other aspects make it unnoaticeable.
Breakfast is ok, better than most similar hotels is Turkey, but some fresh bread wouldn't hurt.
