Barbara's place is perfectly located near the heart of Plaka. And while it is near everything you need as a tourist, it is also on a quiet street. The best thing about the apartment is the rooftop, which gets plenty of sun and offers a great view of the Acropolis. We (there were two of us) didn't really make use of the apartment's living and dining room, but there's probably enough space for a family or group to hang out comfortably. Also, Barbara was super quick and positive in replying to all of our questions.
