Given the description and the pictures our (5 friends visiting Istanbul) expectations were pretty high. We clearly did not fit comfortably in this apartment, even though we should have, according to the description. WiFi is not as fast as described. Place was not the cleanest, but we've seen worse. It certainly needs some love, especially the garden: it would be a lovely place if it weren't left to itself.
That said, the location is calm and birds chirping wakes you up in the morning (positive thing). It is very close, on foot, to the main attractions.
