It was great time staying at Hatice's apartment, it is very close from the tram station, also close from Istiklal Caddesi.
The apartment has everything you need, 2 lovely bedrooms, Wifi, heater, A/C, Water fountain etc. But mostly, THE VIEW IS AMAZING!!
Hatice is also a great host, she got all the transportation arrangement for us from the airport and later to the airport. It was very convenient staying at Hatice's apartment.
I definitely recommend staying at her place if you are coming to Istanbul.
