Cansu's appartment is very well kept, nicely furnished and perfect for up to two couples plus a fifth person - but you may want to stay in two here, as it is a marvellous and cosy place. The views from the balcony on the Bosporus are just spectacular and the pictures she provides in her description are by no means exaggerating.
Cansu herself provides exact advice on arrival and is very helpful and kind.
Full recommendation!!!
Please note that the fantastic view comes at a price: you need to climb down the hills whenever you want to move (and climb up again when returning) or send a taxi driver google-map coordinates, as normal taxi services would have difficulties to find the place.
You may want to verify internet availability. We did not find it at first strike, but you don't miss internet at a place like this!
