My friend and I were in town for 2 nights to check out Athens before heading back to the states. This place was PERFECT. It's only a few minutes from the Acropolis and Gazi (not sure if I spelled that right, but it's where the nightlife is). It's also only 2-3 blocks from the metro, which was extremely convenient when coming in from the port and leaving for the airport (only a $10 ticket).
The place was extremly clean/modern. We used the washer and the air conditioning was a relief. I highly recommend this to anyone looking to stay near the Acropolis.
Also, not that it applied to us, but there wa a crib and baby table just in case you're traveling as a family!
