The room is very cozy, it is located on the first floor and the hosts are living on the second. The first floor has a personal bathroom and shared kitchen. In the room, there were a chair and table, which you can use for work but if you work from home every day this might not very comfortable. When I was at the place, it was a bit noisy outside so if you spend time at home or you are sensitive to noise, it might be not the place for you. But at night it is very quiet.
Location:
It is quite near to the sea and marmaray station. The location is a bit far from Kadikoy center but 10 minutes to the caddebostan area and shops by car. The area is good for a long walk along the coast.
There is a nice cafe just across the street - Sultan, pharmacy and shops are all near. There is a night shop just in front, and a private hospital and emergency are not so far. You can use scooters to reach the subway.
The hosts were good at communication and helping to solve problems very quickly. You might want to clarify about the air conditioner before booking since when I was there it was broken. Hosts were very fast at providing alternatives though. Also, there is no straight seaside view from the room but you can see the sea if you look on the left from the window
