Location was good and as mentioned, two supermarket are open 24 near the apartment and close to metro and bus station and kadikoy shopping area.
The place is nice, cozy and clean and Beyazit was very welcoming and accepted to have additional guest for more money and helped us with luggage upon our arrival.
However there are two issues, there is additional stair you have to climb in order to get to the apartment which was difficult for my mother, other thing was the crazy seagulls that would not let us sleep at night 😆😆 but anyways it was a nice stay and I would recommend it.
