Communication with Derya was very easy, she was reassuring every day if we are fine and do not need anything. Flat is small but with absolutely everything you could possibly need from fridge, washing machine, hair dryer, iron, air conditioning, extra sheets, towels, or even extra heater... kitchen has also everything. It is very close to Istaklal street and Taksim metro but very quiet, especially the bedroom. Lot of good food options around too. I would stay here again if we return to Istanbul :)
