Great location, straightforward to reach any place you may need. The host was easy to communicate with.
The apartment itself was not in perfect condition. I wish to see it a bit renovated.
Also, it was really cold inside. The bathroom sink was out of hot water for some reason.
I'd say it's a good place to stay for a big family or friends, to have walking distance to Taksim sq. But I would not stay for a long time, not much than 2-3 days.
