This 4th floor walkup is in a terrific location right below the Galata Tower. There is plenty of room and lots of windows to see the surrounding area, plus an upstairs terrace with a 360 view of the city (especially good at night). Kadir was our very good host and was easy to reach if we had a problem.
We stayed here for 4 weeks while exploring Istanbul and the apartment has everything you need for a very comfortable stay. We did arrive at the height of the summer weather, so it can get a bit warm, but the windows provide adequate ventilation and a nice steady breeze to cool you off during mid-day.
The kitchen is well stocked for feeding an entire family (up to 5 or 6) and it's got 2 bathrooms with terrific water pressure. The living room is very comfortable with a modern vibe and the wifi is especially helpful as you'll want to look up what restaurant in the neighborhood you'll want to have dinner.
The evening hours can be a bit noisy on the weekends, but because you're high up, the noise dissipates quickly. The washing machine came in handy and there's even a whirlpool tub to soak your muscles after hiking around this international city.
There's a grocery store about 100m away, and you can reach virtually anywhere else by tram, bus, subway and tunel/fenicular.
You won't be disappointed with this choice for your Istanbul stay!
