There were two negative (to us) things about this place. One of the main reasons we booked this place was because it had an elevator. The elevator was not working when we got there and, to be honest, doesn't look like it's worked in a long time. Nasos did post a note recently on the listing that the elevator had stopped working but did not notify us directly before we arrived. He also did not offer any refund or other compensation for the elevator not working.
The other negative thing is that the building the unit is in is rather scary looking. There is a gate into the building which is locked at night and another gate on the floor where the unit is that is also locked at night. There are homeless people sleeping across the street. The stairways are dimly lit and, in the case of one floor, not lit at all.
The unit itself is very nice and has a wonderful view of the Acropolis. The room is spacious, clean, modern and comfortable. The location is great - within walking distance of the Acropolis, a subway station, a hop-on/hop-off bus stop and many restaurants.
Nasos arranged for us to be picked up at the airport and dropped off in front of the building. Our driver was extremely friendly, knowledgeable and helpful. He also arranged a trip to the airport. The price was less than a taxi. Nasos was very friendly and helpful as well.
If you don't mind a scary looking building and climbing five flights (over 100 steps) of a tight circular stairway that is dimly lit, this a nicely appointed unit with a great view and a great location.
