I made a reservation for my parents who haven't traveled much on their own and don't speak fluent English, which made me a bit nervous.
To my surprise, however, they 1) found Anna's flat from X95 bus stop very easily; 2) had no trouble finding supermarkets, shops and touristic destinations that are really close from the apartment; 3) were very content with Anna's warm welcoming and perfect details (bread, Greek yogurt, and homemade jams, etc) on their arrival; in sum, they were so happy with staying at Anna's place!
Furthermore, they said despite the central location, the noise wasn't a problem that interrupted their sleep.
Taking into account the good experience of my parents as well as very attentive and informative host, I would definitely stay at Anna's flat when I go to Athens.
