Tolga's place was as advertised. The place was very clean and all the listed amenities were available. He was extremely responsive and very helpful in providing recommendations for getting around the city.
The apartment location is perfect if you want to be close to Taksim square (10 min walk uphill) and Bosphorus (10 min walk downhill).
There are some things I need to point out... First, there is no microwave oven in case you plan on warming up leftovers. To be fair, it isn't listed in amenities but I'm sure a lot of tourists assume any room/apartment has one by default. Next, the apartment's stairs are not elderly friendly. It is a common style in old buildings but if you have someone who has issues using tall narrow stairs, I recommend finding a place with an elevator or a place at the ground floor. Finally, the apartment is in a residential building. Neighbors do renovations, move around furniture, and they have kids. Expect some noise especially if you like to have midday naps.
