Anna & Rodanthie are excellent hosts and very accommodating. The apartment is adorable, clean, and very easy to get to from the syntagma square metro stop (easy access from airport and Piraeus).
Anna & Rodanthie are readily available through the air bnb PM system, so any question I had was immediately answered.
One thing that is really important to me is that when a place "has internet" it should be working internet! If this is important to you, too, then you will be so pleased. It's lightning fast there!
So: cute apartment, awesome hosts, centrally located, easy to get to, great internet. One star for each = 6 out of 5 stars. They surpassed my rating system.
