The location is okay.
If you go up the hill directly, you'll reach the main street. It's equally distant from Osmanbey, Nisantasi and Taksim, which, in my case was a good thing.
It's not a private apt. When you reach the landing of the stairs (2flrs up), there'll be a door to your left for the bedroom, a door in front for the living room, and an open area to the right for the kitchen. From the kitchen, you'll be able to enter the bathroom.
So, your "space" is accessible to all visitors of the bldg.
When I discovered the state of the space's plan, I asked to check if I'm on my own, in the whole bldg., and was told that there are other ppl. which made my stay stressful.
I asked if there was a hairdryer, and they said yes. But there wasn't. I repeatedly asked for one, but never got it.
I had to ask for instructions for my check-in few hours before my flight. I landed at 2am.
The dishes and the bedroom floor weren't clean.
There's no hot water in the sinks, only in the shower.
