I loved this place! I liked it so much I stayed for many extra days from my original plan. The interior is just how it looks. The colors and the style of decor are so comfortable it really feels like cool apartment home.
Handan is excellent with communication and was extremely helpful on several occasions - I lost the keys and was stressed out but they came and let me in without any issue. Every message was replied to within a couple of minutes.
I absolutely love the neighborhood. Taksim, hundreds of restaurants and cafes and shops are just a few minutes away. It's a five minute walk to the metro and a three minute walk to busses that you might take. There is a little fruit market around corner and a Kebab kiosk less that 50 meters from the apartment door.
I feel like it's important to say that when you first arrive in the neighborhood or especially if you walk from the bus you might think "oh, this looks crazy" - there is a really big hill and the streets are narrow and everything is lively and people drive crazy - but, don't worry! That is Istanbul!
I think you will find the neighborhood charming when you experience it.
I would 100% stay again if I come back to Istanbul.
