If this what you are looking for, you have come to the right place. The hotel is very conveniently located to Athens airport so for an overnight stay it will be perfect.
The rooms seem to be tiered in categories (superior, deluxe, executive, etc.), which you can only access by your key. Our superior appeared to be on the lowest end, not sure why. The room itself was fine, spacious with a good bathroom with both shower and tub and a comfortable bed, but it could do with some minor refurbishing and a good cleaning particularly considering the steep price you pay.
There is no place to get a snack or something to drink outside of their restaurants, room service or of course the airport so if you are arriving late, plan accordingly.
Breakfast, which was included in our price, was a wonderful surprise with good variety and several stations.
For the convenient location and lack of other hotels near by, this is a fine choice but do not expect 5 star or Sofitel standards.
