Stella and Nik are excellent hosts. This apt is in the best possible location with three great bars right below. Lots of action around this house and lots of fun bars/restaurants to see. If you want to experience Athens downtown with the nightlife, there is not better place. We stayed here with four kids, and we were able to venture out as soon as the kids slept. 10 mins walk to acropolis, 10 mins walk to great restaurants.
Stella and Nik also helped us reserve rides from the Port and to the airport as well. There was no hassle in the rides they arranged. We tried to organize a ride ourselves, and that did not go as smoothly.
Only drawback is that this apt has only one bathroom. We were 10 people, so it took a long time to get ready.
Overall, I will recommend this location and house to everyone.
