My fiancé and I really enjoyed our stay at Christos' Airbnb! It's about a 10-15 minute walk uphill from the nearest metro station, but we later learned there are buses, which drop you off less than a minute away from the apartment! The apartment is super cozy and perfect for two people- it was a bit smaller than I expected, but that wasn't a minus- it actually just made the room cozier.
The balconies are the highlights of this Airbnb. We ate breakfast every morning on the balcony and it was wonderful waking up to a view overlooking the city of Athens (on one side; the other side has a great view of Lycabettus Hill). Overall, we really enjoyed our experience :)
