Rıdvan is the host you are looking for.
Helpful and always reachable answering all questions, even if not related to his place.
The House is in an unbeatable location just minutes away from all public transportation and from Taksim Square, u just have to know that the way to Taksim is uphill as usual in istanbul.
Two floors with lots of space and lovely interior.
Just the bath needs some work as the shower cabin looks a bit moldy.
I can just recommend this property and its owner.
thank you Rıdvan
