This is my fourth time in Istanbul with Airbnb and they all went great, but Gökhan's place just ranks on top. Checkin was easy, the place sparkling clean, CALM neighborhood, 2 min walk from M2 metro (Şişhane) and 5 min walk to (Istiklal), tiny bathroom but the other 2 rooms were more spacious than expected and very well decorated and the furniture was really comfy and all amenities were as described. We didn't get to meet Gökhan in person but he was responsive 24/7 and he even gave us tips about different stuff before we even landed! If you're looking for great value and the perfect stay in Istanbul, you now know where to go.
