We sure enjoyed our stay at the apartment, It was very cozy and welcoming. şişhane metro at a walking distance and Galata tower and its night life which we enjoyedvery much. Istanbul can be noisy but the apartment was nice and quiet when the windows are shut.
We were 3 América females traveling and always felt safe in that neighborhood.
Handan is an excellent host. We will stay there every time we go back to Istanbul.
We recommend that you Learn the metro route before heading out there its save you so much time and money.
