We stayed here for three nights and it was absolutely brilliant experience. We liked the flat and the district - it is just perfect for the lively weekend!
Mesut was very supportive with information about Istanbul, reacted very fast on every question regarding the trip and the flat.
Its 5 out of 5 for me, i recomend it!
The only pre-caution for ones who is booking the flat for parents or other seniors - it is on the 4th floor which can cause some difficulties for old people climbing up and down.
