I go to istanbul every year, this is probably the best house i have been in.
Reason are:
1- transportation is very close, uskudar square is 300 meters away, where you can take a metro or a ferry or even bus to anywhere in istanbul
2- very comfortable house , well designed and cozy.
3- house is near the sea. During my stay i used to drink morning coffee everyday by the best view ever
4- host is very responsive and helpful.
Will definitely come back!!
