Safa is a very kind host.
We had some trouble in finding the place on the first day, because the directions we received through internet where not extremely clear. Bus safa was kind enough to expain us on the phone where to go.

The aparment is clean, spacious and with all the necessary amenties. A bit noisy maybe, but I guess that is the case of every place in Istanbul.

The location is excellent, 1 minute from Taksim square, but in a relatively quiet street and next to shops and supermarkets.

I recommend Safa, just make sure to have a detailed and exact expalantion of where the place is before you start your trip.
