It's not worth it.
There is literally no sound insulation whatsoever, you hear people literally breathing the next rooms, the photos make the rooms look decently sized when they are in reality awkward tiny and the wifi connection is just tragic.
Don't stay there unless you're a smoker, the smoke is inescapable even inside your room. Also they have ants...
It's in Beyoglu very close to Istikal street which is great but the hotel itself is on a very sketchy little street that made me feel kind of unsafe.
Not worth it. There are plenty of nicer and cleaner places at a better price in Beyoglu.
Basically I regret having spent my money to stay there and wish I could get my money back.
