Ertan's place is as nice as you see in the pictures and has an amazing location, just few steps away from the middle of Istiklal Caddesi - making it easy to go both directions, Taksim and Galata.
Check-in, communication and availability were great, Ertan gave us an additional cooking plate since one of ours was not working well.
The place has also a common laundry machine which may be of importance when staying there in summer or for longer periods.
I would definitely recommend this place for people that are looking for something that has more of home comforts than hotel ones.
