We were more than pleased with our staying in Istanbul and we couldn't had picked better. The whole packages of services (breakfast with terrace view, room service, enough space with optimal organization, more than sufficient for a couple, clean towels with basic cosmetic, splendid view, central location, very comfortable bed & clean sheets, etc) exceeded our expectations and I think this was the best money spent for accommodation so far.
I strongly recommend Alihan and his locations for a very good quality and price rate, you will not be disappointed.
