The apartment was exactly what we had hoped for. It was spacious, impeccably clean, and very comfortable. It was close enough to all of the major sites that we could easily walk everywhere.
The neighborhood as a whole left a little to be desired, but because of its proximity to other neighborhoods (and the bakery across the street that we fell in love with) the neighborhood really wasn't an issue.
While Maria wasn't there to meet us, her neighbor Danilo let us in and explained everything. Also, Maria gave us excellent directions of how to get to the apartment from the airport.
If I were to travel to Athens again I would definitely stay there. And I recommend that anyone who is looking for a comfortable and quiet place to stay while in Athens, stay in this apartment.
