Everyone will tell you Kolonaki is the best area to stay in (and most expensive). This Airbnb was very good value in January, though. Very responsive and respectful host. Easy, self check-in.
Awesome views of the sunset from the balcon: there is a private balcony (but not as good a view) and this is connected to the shared balcony which feels like a private one because nobody else ever goes there! Definitely recommend.
Quirky, small room. With room-tall windows.
Thanks Leonidas! :)
