Very close to the subway and walking distance from the city center and main sights (Acropolis included).
The the room and the entire building were very clean and modern - in contrast with the dirty city of Athens.
We had apt. 106 - at the top floor, and we also had a nice, well lit, and modern rooftop terrace that we shared with the rest of the guests/tenants in the building (but which seemed somewhat bright when trying to sleep).
On the downside, the shower was clogged with hair and dead skin and had an odd odour, and even we talked with Nelly about the issue and she promised to send someone to fix it, we did not receive any confirmation if the issue was addressed (and it didn’t seem to have been).
In addition, despite the acomodation being very central, there is an issue with the overall appearance of the neighborhood. The locals told us repeatedly not to worry about it, but the area is very, very dirty and it looks pretty dangerous. At least we had no unpleasant incidents.
Overall, given the price, the closeness to subway and main sights and the cleanliness of the bed/sheets, I would recommend the property for a short stay in Athens.
