We had such a nice stay in this nice and comfortable airbnb. We had everything what we needed, 2 bedrooms and an additional living room to chill on the sofa. When we arrived everything was super clean and we even got a little welcome gift, as well as free coffee and water. The airbnb is very close to the main shopping streets and the more interesting districts of Istanbul. We either walked or took the bus.
One of the rooms is next the street and it can be super loud in the morning. So i recommend to take e.g noise canceling headphones with you
