A very nice (and comfortable!) apartment located in a very vibrant neighborhood. Lots of shops and restaurants around, and close to most all the sights. The rooftop terrace has a wonderful view of the Acropolis. One of the big reasons I choose airbnb over hotels is because you can "live" in a neighborhood, and you're not stuck in the a sterile room. Also, access to kitchens is a god-send for those of us who sometimes like to cook. This fit the bill.

One word of caution, though- it's right across the street from some sort of club. On Friday and Saturday, the music and laughing started around midnight and went straight on through till 7 am both nights. You might want to bring earplugs if you're there on a weekend.
