We enjoyed a wonderful stay at Isak's place. The apartment was as advertised and Isak was a fantastic host -- very accessible and helpful if issues came up. The apartment is modern with lots of light and nice design touches throughout, including a beautiful bathroom. The building itself appears almost new. The apartment is on a small residential street off of a main street, and is located within easy walking distance of several great neighborhoods, including Galata, Istiklal, Karakoy, and Cihangir. The one drawback was the noise; the apartment is near a playground and faces the street, so it can be pretty loud at night. Bring ear plugs! All in all, highly recommend Isak's place for anyone interested in coming to Istanbul.
