I am writing this review after staying there for 9 days, with another 6 adults (my family).
Approaching him was okay! He always get back to me only through Airbnb message within few hours. There was not a serious issue about that.
He is kind and helpful. You can always go to him for some hint on your travel and he is ready to help you out.
The location is really good and walking distance to most of the touristic areas, supermarketas and great restaurants. However there is a little detail here. As the place is relatively near the marmara sea, so it's down the hill. To access most of the place you need to climb a hill to reach to tram station. The walk is easy for young people but for elderly it can be dificult. If you have baby stroller it can be a real headache. So, take that into consideration.
But the main thing I didn't like was the room setup. The picture does not represent the reality. You can see a big living room which is not there due to different placement of furniture, like having extra bed in front of kitchen. So, everything is more compact than what you see in the pictures. Also the house is in the third floor, which kinda bothered my old father to climb the stairs each time.
Also, you need to know the house is like two different units separated completely, having next to next door.
So, I hope Cesim consider to include more details in the explanation and include pictures that really represent the place.
Apart from those, the house is very clean and get regularly cleaned by the staff each 2-3 days.
Last point, my family changed their plan 1 week before the trip and they had to go back earlier. I texted him to stay there shorter time and asked him to allow me to change the booking. Because I don't wanted to stay in a big place just by myself alone. He refused the request. Of course I can't complain because it was his absolute right to reject my request. But, I wish he would accept my request and make my trip more memorable.
