We stayed in the apartment for a month and it was generally a good experience.
There's a bus station just below the apartment (can be noisy at night as a result), and all major transportation lines are within walking distance, so it's very conveniently located. Shops nearby abound, although not good restaurants (plenty of kebab outlets, though).
The area is more conservative and not very touristy, and after some unpleasant experiences, I'd recommend not walking woman-alone at night.
The apartment needs maintenance but well-suited for general needs. The owner was very responsive whenever we had an issue.
Wi-fi in the apartment is virtually nonexistent, but the owner kindly let us use his office upstairs.
Overall, very kind and helpful owner. Thanks Ihsan!
