Theodoros and Lena are probably the best hosts I’ve had in my Airbnb travelling experience, they are devoted to making sure you feel home and have everything you need, arranging, helpful and kind. On top of that, their devotion can be seen through the apartment; what you see is what you get. It is clean, well maintained, functional, comfortable, and warm. We stayed there for 2 months, and it was perfect, you feel home and have everything you need.
The location is central to everything, within 20 min walking you reach all the main spots. If you want a typically Greek environment, then you should check other areas of Athens.
I would definitely recommend the apartment ! :)
