This place is a great place to stay on your visit in Istanbul. The room has everything you need, the location is AMAZING as it is only a 5 minute walk to the tourist sightseeing places, and close to public transport if you need to go further than that.
Kamuran is an amazing host, she was really responsive, as we arrived late at night and texted her, and she was immediately trying to solve our problems.
We arrived and we did not have Wifi, but it was fixed and the next morning everything worked great, although the wifi is a bit slow, so keep that in mind if you have to work remotely.
The only disappointing thing is that the pictures are a bit misleading, in which they show a kitchen, but our room did not have access to that kitchen. This was bad for us, as then we had to have all our meals out, and could not cook breakfast, or keep things in a fridge, for example.
Besides from that, the place is great, and the host is amazing. Would recommend.
