Nicola is a great host! very friendly and helpful, he helped us by giving us recommendations on what to do and where to eat, he even kept our baggage in a safe place until the time of our flight after checkout.
the place is in a great location, very close to taksim square and also convenient to go to all major sites. however, the place was a bit smaller than it seemed in the photos and the furniture is worn out. there are a few windows but they all open directly to the wall of another building, so no fresh air or sunlight, and the parquet makes squeeky noises whenever you walk over it.
