Lilly's apartment is in a great location, right by Syntagma Square and very easy to get to/from the airport, either by the Metro or the X95 bus. Lilly and her friends were great hosts and graciously allowed us to keep our backpacks at their office for a few hours since we arrived in the morning and didn't want to walk around with them until we could check in. The apartment was spacious and clean and, despite being in a busy area, was also very quiet. Meat the Greek is close by and has AMAZING gyros and souvlaki. I highly recommend this apartment to anyone visiting Athens.
