Mehmet is a nice host, he made the check-in and check-out very easy. He is also very responsive, helpful and has a lot of tips about visiting/eating in Istanbul.
The place is in a nice location, it was easy to get to the main touristic areas and we always felt safe around the airbnb. There are also restaurants closed by, some coffee places, small supermarket and even a laundry place closed by in case you need to wash some clothes. We stayed in the same building twice since we went out of Istanbul and back in the middle of our overall trip. We got two different rooms from the same host, both were clean, spacious and with comfortable beds. You could hear some noise from the other rooms, but in general we had quite neighbours so it was not a problem for us.
Overall, we enjoyed our stay and recommend this place!
