Ergun is good host, friendy and pleasant person to deal with. He met us nearby the house building, which would at first have been harder to find ourselves. Ergun helped us get upstairs into his place and provided information about location of grocery stores and cafes. His apartment is located at walking distance to Taksim metro station, Taksim square and main street. You can find numerous cafes, restaurants, shops and outlets where locals spend time and at good value. You can walk up to Eminonu along the main street, Levent is few stations away as well as Sultan Ahmet. It was quiet and okay place to stay in Istanbul with kitchen and fridge to cook basic stuff. I can positively recommend Ergun for his hospitality.
