This appartment is great : great space, very clean, perfectly located and very handy.
We were 7 people : 1 couple, 4 children and one adult. Everyone had his own space and we never felt cramped thanks to the 3 bedrooms.
The living room is a little bit small when we had dinner in it, but manageable.
The view is great.
It is ideally located in sultanamet, tram is only 5 min walking distance, so you are in another area of the city very quickly, with less tourists, and better prices (fatih, nurusmanyia, suleimanyia..).
Even on foot it is not far at all.
I highly recommend family to chose this place. Ali even arranges the trip from the airport at very fair price.
Need help? Ali will be available to help in case something is wrong in the appartement (rare) or if u have any questions.
Enjoy your stay in Istanbul !
