I can definitely recommend this apartment, it's cozy, fully equipped, quiet.
The location is great - the street is quiet, but there are a lot of good local restaurants, supermarkets, pharmacies and so on. In 10 minutes walking there is a big mall with hypermarket and shops. 10 minutes walking to the metro with trains to Sabiha Gocken Airport, or Hava buses to Istanbul Airport.
Also, Ömer is so great and kind host, thanks for his advices, patient and openness
