Eugene's Place is definitely the best one in Athens, the view from balcony is amazing!
I would love to come back again and stay more days next time.
Ifi & Emilio made this place very clean and well-organized, they even have maps of their own, which is very sweet and convenient.
Athens is really small and walkable, I didn`t take any transportations to visit Acropolis or other views.
However, it's located in uphill, need to walk up a little bit, but the view from the mountains worth everything.
