Kartal is an excellent and honest host. From the start he was very flexible about check in and throughout my stay (10 days) he was quick to answer any questions I had, no matter what time it was. The apartment is in an excellent location in Kadikoy, a quiet tuckaway in between areas populated by stylish bars and cafes with mostly students or young people. Transportation all around the city was very easy. Rooms are more spacious than I expected from the photos and very clean. Amenities like irons, drying rack, extra towels, are provided.
