Very nice place that was very clean and the owner is extremely helpful. It's well lit and has good air-con. Has everything you'd need for your stay. The host was very helpful and was always available via Airbnb.
One point that cannot be helped is the surrounding neighbourhood.... There is nothing to suggest that the neighbourhood was unsafe, but it did have a run-down appearance and neither of us felt comfortable walking around after dark. Many nearby streets were not well lit and there was a lot of graffiti on the walls. Obviously the host can't be held accountable for this, and maybe this is common for central Athens, but if you're a lone female traveller I would take it into account.
