I visited Istanbul with a friend for a weekend, and our staying at Daniel's place was just perfect. The apartment is cozy and comfortable, it is a rooftop with an amazing view of the Bosporus by the bedroom and a lovely terrace facing Galata tower on the other side of the house.
Daniel's apartment is well connected to public transportation system: 2 min walk distance from Tophane tram stop and 5 min walking from Sishane metro station, the neighborhood is full of cafes and restaurants.
Daniel's is a lovely host, always available and happy to give us suggestion for places to visit, we really couldn't ask for more

I highly recommends Daniel's place and I will definitely come back if I have the chance.
