The neighborhood is ok but at first, I would not have said that because you have to move in dark and let's say empty areas to arrive home (from Taksim main street, you have to go down a bridge and walk for around 10-15' to go to the flat).
Being alone and being a girl I was scared initially, then you just get used to, so just run home eheheheh.

About Merve, she is very nice and gentle.
