I lived in this apartment for a month.
Some comments that will be helpful to the tenant:
1)Serkan is a responsive and friendly host, always helpful if needed, and won't bother if you like privacy.
2)The kitchen has everything for cooking, but there is no dining table, you have to eat either in the hall or carry everything to your room on the 2nd floor.
3)It takes 15 minutes to the subway, but Istanbul is located on a hilly area. And from home to the subway, you will go uphill and back downhill.
4)The apartment is located in a residential area, close to 1 store. so if you wanted to go to a cafe, it is a walk to the subway (uphill climb).
5) In February, despite the fact that the heater was at maximum, the room is cold. (This information for those who are constantly freezing)
The room is worth the money.
