The apartment of Deniz and Marco is just perfect. It is located next to the Galata Tower and the neighbourhood is really nice. You find a lot of restaurants, bars and small shops nearby. The terrace, which is one floor above the apartment, has a stunnig view. You have to share it with other guests of the house, but there is a lot of space for everyone. I highly recommend the apartment.
Thank you again Deniz and Marco. I would love to come back someday.
