I recommend this place, located near the Galata tower and near the metro. It’s a beautiful renovated appartement with all you need, comfortable and most importantly it’s very clean. There’s is AC. The staff are really kind and helpful. We stayed there for 5 days and we had a great time. When reading the comments i thought it will be really noisy because of the location but it wasn’t that bad, we were 3 persons and we all slept well. If i ever come back to Istanbul, i will try to rebook this airbnb!
