I was in Istanbul for work and travel, and felt very welcome at the Buhara Inn. The roof terrace was one of my favourite places during my stay in Istanbul - waking up to an amazing, tasty and fresh breakfast overlooking the blue mosque and the Bosporus is just great!
Everyone at the place is very friendly and happy to answer all your questions, my room was small, but very clean. The bed was comfortable. The place is conveniently located in the historic part of Istanbul, close to the blue mosque, a small bazar, the Aya Sofja. Its also close to Sultanhamet tram station.
I would recommend the place to anyone.
