SOFYA was a lovely apartment and very clean. We were welcomed by Anil who was very helpful and kind. He also made it very clear we could contact him for anything, and we did. His response time was very quick.
The apartment's location was more towards the new district for travelers who want to be close to shopping. However, the public transportation is pretty close to get to wear you need to go. Also if you are looking for something quiet I wouldn't recommend SOFYA, but the noise isn't so bad especially if you are traveling to Istanbul to embrace the culture it's great for that. We were hesitant to be out after dark in the neighborhood but we soon realized that everyone is exceptionally friendly!
It was a beautiful city with lovely people and I would recommend this apartment!
