We had again a great time at Dilek place. The communication was easy and quick and the place looks exactly like it does on the pictures.
The neighborhood is very conveniently located and had a lot of life within walking distances. However, it was very quiet inside.
The apartment was walking distance to many tourist attractions, and it was close to a taxi booth and to metro/bus/ferry stations to get you to the ones further away and to get you back to the airport.
This is definitely the perfect place to stay in Istanbul.
