Helen's place is lovely decorated and close to all amenities. The neighborhood is chic, with numerous cafes, bars and restaurants of all price ranges. Personally, it is much preferred to Plaka. You literally can walk anywhere (Acropolis, National Archaeological Museum, etc) within minutes. On top of that, Helen is a great host, who respond to our needs promptly. As a bonus, her sense of humor is infectious and lighted up our mood after a long flight to Athens:) I would definitely recommend this place to everyone.
