Apartment was as expected - great location with wonderful views from the private rooftop terrace. Our kids really enjoyed the two twin beds in the 2nd bedroom, since they prefer that configuration over sharing a double bed. Harry arranged a taxi transfer with preferred driver Panos, who met us at Arrivals and gave us a nice ride to the apartment. Harry's associate Hani (Hanni?) met us with the keys, gave the grand tour and pointed out key locations/local highlights on a map of Athens. He then provided a brief orientation to the neighborhood and led us to a nearby bakery (which had a great breakfast and baked goodies).
This is a very walkable location. As others have pointed out, it is within 5-10 minutes walk of the Acropolis, which is good in that you are close to the action without being disturbed by it. There are nice local restaurants nearby and they are generally lower-priced than those in the main tourist zone. A friendly little bottle shop is next to the Thai place on Veiku street. We stopped there one night on our way back from sightseeing to pickup beverages for the rooftop. In addition to bottled wines and other spirits, they sell some Greek wines by the cask which are inexpensive that you can try before you buy.
Since we were in the middle of our overall trip, we used the washer to do our laundry. I was concerned about the absence of a dryer, but the apartment has 2 big drying racks to hang your clothes (pro tip: try to pack quick-drying fabrics and use the highest spin cycle). If you are visiting from the US, you should know that the typical washers installed in Euro kitchens are much smaller and also take 2-3x longer to run a cycle that what you might be used to, so plan accordingly.
