Sinem is a beginning but a promising host. There were a couple of misunderstandings in the beginning, but she corrected mistakes fast (like the wrong address) and she went out of her way to make my stay as comfortable as possible. For example, she called the construction workers in the building to ask them to pause the drilling while I had a work meeting. The really noisy construction works only happened for several days, and they were not Sinem's responsibility. I only wish Sinem had warned me about them before I moved in. Luckily, the works ended at 5 pm and the evenings were quiet.
As a person, Sinem is very friendly, open and helpful. She reacts fast to the guests' needs and tries to find the best solution if there is a problem.
The pictures of the room in the add were a bit confusing for me. In fact, Sinem rented out two rooms. So, if you can come and have a look before moving in, I recommend to do that to avoid surprises. One room is smaller and has the windows facing other windows.
Another room, the one I stayed in, is spacious and sunny. The temperatures were fine for me in the beginning of May. However, I imagine that it may get really warm in the summer. There is no air conditioner in the room.
Also, remember that this is one room in the multi-room apartment. So, you will be sharing a bathroom with Sine, her family, and another guest. One bathroom is really spacious (and clean) with a toilet, a normal size sink and a jaccuzzi like tub+shower. There is a second toilet room with a mini sink. In the main bathroom there is also a washing machine you can use.
A huge bonus is an elevator! (Many buildings in Istanbul do not have one, so the travelers have to carry suitcases up the stairs).
The location was amazing! it is close to the embankment where you can run, walk, cycle, or just sit down and enjoy stunning sunsets. The cafes, restaurants, bars, stores are also very close. (Still, the apartment is quiet! No disco sounds at night). The apartment is also about 6-10 minute away from ferry stops and HAVAIST 14 bus stop (this bus is a cheap and very convenient way to get to Istanbul Airport). Overall, the location is just PERFECT!
