It was a pleasure to stay in Chihangir's apartment. It is comfortable, clean and has everything needed for a short and long stay, including for example washing machine, microwave and excellent working central heating. You can hear the waterboiling/the heating system standing in the living room, but i wouldn't say it is too loud or disturbing. It didn't bother me while sleeping at all. The apartment is very well located, the neighborhood is calm and feels safe, with a mini-supermarket just around the corner. At the same time you can reach the taksim square with public traffic within 5 mins and the streets with lots cafès, bars and bigger supermarkets within ca. 7-10mins.
Chihangir is a wonderul host, caring and helpful, who answered my messages very fast and helped me with a luggage. I definitely can reccomend this apartment.
