Location:
Great location, close to the Galata tower (you can see it from the window), lots of good cafes in the area, and close to nightlife, the apartment is on a side street so it's relatively quiet.
Apartment:
It's on the 3rd floor and not big, but it's really comfortable and well designed.
There's a kitchen with all you need.
One con is the water heater, it's electric so you need to have a weak water pressure for it to be really hot.
Host:
The host was really responsive and helpful, the apartment was very well equipped and any problem we had was responded to fast and the host went out of their way to help us have a good stay.
Really enjoyed and would stay here again if I returned to Istanbul
