Ari's home is really lovely. Beware - there are many steep steps to get to the 1st floor of this home. Not necessarily a problem unless you're traveling with your 81 yo mother.
The 2 story living space is unique, especially the rooftop bedroom & patio. This floor definitely made our stay fabulous. Fantastic view of the Acropolis & beautiful al fresco dining. There is also a full bathroom on this floor with a great bathtub complete with Acropolis view. The first floor has 2 bedrooms (1 which has no windows) & 2 baths with showers & the kitchen. All bedrooms have AC & TV. Also, extra touch - Netflix.
Don't be too put off by the area getting to the home. It's located in the Thessios area which is the Athens Flea Market so streets are filled with locals selling used items. When you are not expecting this, it's a bit unsettling. But once you walk around the corner, you are in Monstariki Square which is filled with 100's of quaint outdoor cafes. Very fun & authentic.
