This was a very nice and comfortable apartment with all the modern amenities. The view from the balcony of the Lykavitos is incredible, and the Varnava/Pangkrati location is a very lively and non-touristy place to stay. I liked that this listing seemed like a pretty typical Athenian apartment instead of a luxury resort for tourists.
There are several amazing restaurants within walking distance (Gepetto, Colibri, O Elvis, and many others) along with a supermarket and pharmacies which should have anything you'll likely need. You're a 15min walk from the National Botanical Garden, Hadrian's Gate, and Syntagma, so you're close to the center of the city, from which you can get anywhere via the metro, but you're in a quiet and peaceful area.
Dimitris was an incredibly helpful host. He will arrange you a taxi or tours to wherever you want to go, recommend great restaurants and places to go, and answer any questions you have about the apartment or about Athens. He is very responsive and will answer the phone or answer messages on Tripadvisor.
If you're looking for a low-key place to stay in a lively part of Athens with tons of good food and without so many tourists, this is definitely somewhere you should stay. Thanks again Dimitris!
