Ozan is a great host; we did not have any trouble during our stay and he made sure he is available if anything, checking via phone even if we did not have problems.
It was our second visit in Istanbul and we chose Fatih for the second time. Close to lots of restaurants and cafes, good bus connection.
One house with 3 floors: ground floor with kitchen, TV. first floor with bathroom (one shower cabin and separate room for toilet, not big, not too small, more than enough) and then the bedroom. last floor is with a couch and TV, AC, small balcony.
Internet speed very good; no interruption; the same with hot water, all good.
