Just go ahead and book. I know—you may want a view of the Parthenon or something like that (which so many have on this site), but for me, I was so happy to have a secure, central and comprehensive small space for my trip to athens.
My time at Andreas’s space was a bookend of my trip to Greece. I started at this Airbnb before traveling to Naxos (and doing some small island hopping) and returned for two days before leaving Greece. You are right by planka, the Parthenon, and the National gardens. Centrally located next to various local restaurants and National fast food joints (which I admit by the end of my 12 days aboard, I just wanted some Starbucks), it is a secure location with a small elevator and easy self-check-in. Many appliances are located in the studio that are helpful and may not be available in a hotel (again at the end of my trip I needed to do a small load of laundry and while I was a little confused with the machine, I got just what I needed). I just really appreciate the space and feel so fortunate for being able to stay there.
