Rifat is a lovely host, he was very responsive and welcoming. He checked up on us regularly and made sure we had everything we needed. The location is amazing, literally a 5min walk from the blue mosque, in the old part of Istanbul. (very central).
The only tiny downside was that the room on the photo was a little bit different than the one we got and it was on the ground floor which could be a bit loud from the people living nextdoor.
However, you should keep in mind that it is on a tiny street but people in Istanbul generally like to hang out on their street in the evenings so we understood it wasn't from the location but a general thing.
