We recently stayed at the Amedros Home in number 4. Check in went very smoothly and we were met by our host who had thoughtfully put some basics in the kitchen for us. The apartment is very centrally located on a quiet street about 5 minutes from all the major sites in the old town. There's a shop directly across the street and a laundry around the corner. With the view from the terrace, the location and a very helpful host, I would highly recommend the Amedros Home if you visit Istanbul. I would certainly book this unit again.
