The house is exactly like in the pictures, and it is extremely well equipped: basics to cook, coffee of all kinds, cookies, butter, juice, water, shampoo, hairdryer, iron, soap for the washing machine, etc.
The communication and arrival was easy and fluid. They offered to arrange a taxi but we took the metro, which was also easy, and cheap. In addition, they gave us an Athens guide they did themselves with recommendations near the house.
The area is residential, local (but not fancy), safe and 15-25 minutes walking distance from the main attractions. We took some taxis to come back at night when we were tired, and paid 3/4€.
The best was the equipment, we felt like at home. The worst, if I have to say something, was that the location was not pictorial/pretty, or at the heart of the attractions , but it served well to visit the city by foot.
