Very close to Istiklal and Taksim but it is not in the safest location. There are bars around playing music all night so you wont have a good sleep. The apt is tiny and and a bit outdated. Tv is old and doesnt have apps like Netflix. No problem with heater and hot water. The host is very communicative. He was very helpful during my stay. That was the only thing i liked pretty much during my stay.
