To break it down into simple pros n cons:

Pros:
1) Excellent location just off Istikal street and Taksim square.
2) Excellent connectivity options all day (public transport, cabs)
3) Halil was very responsive to communication.
Cons:
1) Apartment is functional but definitely Not as nice as it looks in the photos. The bathroom was a big let-down.
2) Apartment is very run-down. Could do better with upkeep.
3) Wifi was an issue. And Halil tried to correct the issues. It was fine while it worked, but kept disconnecting.
Overall - 3/5. But with potential to be much better.
