I have traveled to over 80 countries and have spent nights in all kinds of accommodations. I can say that this one is special.
1) Apartment is clean, nicely decorated, quiet, has a beautiful balcony on the fourth floor, a full kitchen and two bathrooms. It was exactly as described. Our party had four people and it still felt spacious.
2) Location is superb. Hard to imagine a better one. Sits on a safe, attractive pedestrian street with numerous cafes, 20 yards from the metro station, 40 yards from the entrance to the Acropolis Museum, 100 yards from the main entrance to the Acropolis, 200 yards to the Monument of Lysicrates, and 300 yards to Hadrian's Gate. I suspect, location wise, this apartment is situated in one of the best locations possible.
3) View is stunning. From inside the room, looking through the window, was an unobstructed view of the Acropolis. On the balcony, the view was amazing. You have to see it to understand. The Acropolis Museum is so close, you can actually see the exhibits inside the museum from the balcony. Also, from inside the museum, and from the top of the Acropolis, I could see easily the balcony of the apartment.
4) Communication with the host was good at all times and Konstantinos arranged the transport to and from the airport for me.
When I booked, the cost was within range of the decent to better hotels in the area, but the view and size of the place make it a very good value, in my opinion. I would stay there again, without question.
