The place is aesthetically pleasing & has all the amenities of a home (washer & dryer!) while being clean & not cluttered. It's located at the base of Mt. Lycabettus (the path up is right across the street or you could take the funicular which is around the corner) and has tons of markets, restaurants, and shops within walking distance. Also within walking distance of all the major sites in Athens (Syntagma Square, National Garden, Monastiraki Square, Acropolis, Agora, etc). You are uphill in Athens so it can be a pain to climb up daily though personally this was a plus for us as we enjoyed the workout.
A couple of items to note as I wish I knew these things prior to booking our stay. You cannot tell from the photos but this is a first floor unit and the patio is facing the street. From the photos, it appears that there is tons of natural light but it's quite dark in the unit and never gets full natural light due to being at the base of Mt. Lycabettus. With that, there is barely any cell reception (though Elena did mention Vodafone works better there) though there is a landline available to be used for landline calls. We are full time travelers so we work while traveling and it's important for us to have fast & reliable internet. There were times when the internet was painfully slow and times when it just didn't work even after restarting the router several times. We had to go to local cafes to work though we enjoyed getting to see more of the neighborhood.
I loved that it had all the amenities of a home so if you're visiting Athens for pleasure, this would be a great AirBnb due to it's location. We haven't had to take a taxi once (besides to/from airport) as we could walk everywhere. Though if you want to take a taxi, there are taxis right outside as the home is right by the St George Lycabettus Hotel.
Special thanks to Manolis for checking us in, assisting us with a translation, & booking our airport ride with Alex.
