The apartment is taken care by Roman and his friends (3 in total as I believe). We were greeted by Alex who was ready by the building door when we arrived, he spent about 15 minutes telling us all about Athens, showing us the places where he thought we should go, in the map that him and his friends created! The map also included restaurants, cafes and other spots all really close to the apartment. I kept referring to the apartment as our "hotel room" cos that's what it felt like, considering the nice and new furniture, the location and just how clean everything else. Totally worth it for a couple and if you don't wish to spend any money on transportation, as the place is in the middle of Athen's center, close to all the bigger attractions.
