Halil it's a Great Host, and location it's just perfect, close to everything: restaurants, shops, metro, bus, Taksim Square...
The downsides it's that's the apartment is in the ground floor, so you don't have much privacy and it's very, very, very noise around.
Have a carparking in front, that works 24/7. For 2 times we woke up at middle of the night scared with people shouting, arguing there, so we couldn't sleep.
Apart from that, we enjoyed our stay.
