I have been traveling Istanbul a lot and this was my 4 visit since last year and since now I haven’t had such an easygoing place for renting, close to all what you need few minutes walking to Karakoy Tramvay station, around 10 minutes walking to Galata Tower, and few minutes walking to Karakoy Ferry station. The host was very friendly and helpful. One thing worth to mention that there wasn’t hair dryer machine and we asked he brought for us and bought a brand new one . I do recommend and definitely will stay there again.
