Would not recommend it to people who need a clean apartment.
The room (#11 on the 3rd floor) had a smell of cigarettes, the walls had stains (the room on photos look much cleaner than it actually is), the floor had burns from shisha coal or smth else. I also did not like that the water kettle was too dirty.
After I checked in, I asked the host for a refund because the room was different from the one in the photos. Gladly, Sertac agreed to refund me for the rest of the days except the first one. Unfortunately, he did not agree to refund the first day.
Nevertheless, the location is good, wifi is fast. If you stay alone and are also a smoker, then this might be a good option for you.
I found a good suite hotel room nearby for 40 euro/night, so I would say that the extra 5 euro I overpaid per night is worth the cleanliness and a good smell in the room. For this apartment, I would pay 20-25 euro/night, not more.
