We had a great time at Yildiray’s place, the appartment was very clean, spacious and very well furnished. There is a small market 1 minute from the building and with waling distance you can find very cool restaurants, bars, shops and clubs. It was very easy to communicate and the hosts were always responsive. Self check in and check out is also very convenient about it. I definetely reccomend staying at Yildiray’s place for your visit in Istanbul:)
