I was absolutely happy to stay at Efsane's home!:)
Efsane and her family (including cats) are very friendly and lovely – I felt like part of this family since the first day of staying:)
The room I stayed in contained everything needed for good living and working remotely: a big desk, chair, strong internet connection, comfortable bed and a wardrobe.
The place is very close to everything: 5-10 mins walking to very good cafes (especially I loved 'SOI' and 'Kahve Hane'), 7 mins to Bagdat Street, Marmaray (metro) and bus station, 15 mins to the seaside.
Efsane always helped me with everything and gave recommendations about Istanbul. This place is definitely recommended for both short and long term stays :3
