Great location, the apartment is perfect for 4 persons and very clean. Although it is located in a very lively neighbourhood, it is not noisy as the apartment is in a side street.
The bus and ferry stop are very close to the apartment and you can reach any place in İstanbul easily.
Grocery stores with everything you might need are just a stone's throw away. Also, there are countless restaurants, cafés, confectioners, bars and bakeries of good quality.
And not to forget: Ismail is very kind and a great host. Always ready to help when you need something.
