Probably the first thing to say about Sophia's Airbnb is the location - I can't believe how great it is! I came to Athens expecting to use a lot of public transit as I often do, but if you're okay with a bit of walking, most of the major sights (Acropolis, Panthenaic Stadium, Syntagma Square, the National Garden, Plaka, Monastiraki, the list goes on...) are within about a 30 minute walk. We ended up buying a metro ticket with a few trips on it and didn't even use them all!
The apartment is definitely cozy as you might expect, so don't try to squeeze more than two people in. Also it is worth noting that there are a lot of steps in the building and the unit itself, so just be aware of that if you have any mobility issues. Otherwise it's a very cute little spot right in the heart of this beautiful city. Sophia is very attentive and responsive so don't be afraid to reach out with questions. Very much enjoyed my here!
