We had a short but sweet stay at Maria's. Probably the best communication and warmest welcome of all airbnb hosts we've come across. There should be another tier above Superhost because that's Maria.
The place felt like home and we had a beautiful view from the patio. It's centrally located by train to main attractions, easy to get to from the airport (one direct train + short walk), and conveniently located to Pireaus port if you need to catch an early ferry like we had to!
Highly recommend for overall value, location, and hospitality :)
