My husband, two adult children, and I stayed at The Athenian House during the first week of April. We absolutely loved it.
The location in Plaka is perfect -- very easy to walk to the sights, two great restaurants right outside our door (Zorba's across the street and Cafe Melina next door), and a lovely, picturesque area of narrow winding cobble streets and beautiful houses.
It was so nice for us to have so much space -- a large living/dining room, kitchen, and bathroom on the first floor, three bedrooms and two bathrooms on the second floor, plus a finished attic (which we did not use, as there are only four of us -- but would come in handy for a larger group).
The house is beautifully decorated, with every amenity we could want (air conditioning, dishwasher, clothes washer and dryer, a fully equipped kitchen, including coffee makers and coffee, plates, mugs, glasses, cookware, etc.).
Last but not least, Anna is a lovely hostess.
We would go back to the Athenian House in a heartbeat, and recommend it highly.
