Good place for its price at such a great location, for short stays. For long stays there might be some small inconveniences that may bother you - no hot water in the sinks, only in the shower cabin (tankless heater), kitchen in the separate small closet in the stair hall halfway up the stairs (not heated and pretty tight on space), no ventilation in the bathroom (all the steam after the shower will stay in the room for some time), no central heating - but you can use the electrical heaters provided - work fine, the absence of AC did not bother me because it's winter, but may be tough in summer. Also it has windows into the quite busy and noisy street. Internet was fine but sometimes not enough for video-calls (uplink is very weak). But all those minor drawbacks fade away after you get to the roof with your morning coffee and see the Bosporus and bridges and all Istanbul around you!
