EmrE is a wonderful host: he guided me through must-see places in Istanbul, showed maps and explained how to go to grocery stores, ferries, Prince Islands and so on.
The apartment is located nearby İstiklal - the main shopping street, Shishane subway station and Galata Tower. Grocery stores are 10-15 minutes by feet. If you need to work remotely , there is WiFi with a quite good speed.
The apartment has also a balcony facing the inner yard and necessary amenities such as washing machine, boiler, iron, ironing board, 2 umbrellas, a refrigerator etc.
