I couldn't have been happier with my choice of Air B&B in Athens. This sunny apartment is on the 6th floor of a very well maintained building. On the wall of the bedroom, there's a big map of Athens and a list of local recommendations written out by the hosts. That was tremendously helpful to a first-time visitor like myself. The kitchen is stocked with lots of spices if you like to cook there's a good chance they've got what you need. You can walk to the nearest metro stop in about 10 minutes, or you just walk to the attractions. The walk from the apartment to say, the Acropolis takes you through so many interesting parts of Athens that the walk itself is an attraction (check out the Central Market, it's a crazy place). The neighborhood is eclectic and urban, but I always felt safe. I can honestly say that the experience of staying in the Exarcheia neighborhood gave me a more well-rounded feel for what modern day Athens is when coupled with visits to the touristic areas such as Plaka. I highly recommend this Air B&B, so much so that when I go back to Athens next week, I'll be staying there again. It's a great place!
Michael and his family are the loveliest people you could hope to have as hosts.
