This could easily be considered a 5 star hotel.
The lobby area was GRAND, with plenty of quiet eating. The rooms were very nicely appointed, and plenty of features, like in-room luxury coffee machine.
We could see the frigging Acropolis from our balcony, which was just awesome!
Refreshing HOT breakfast was included, which was very nice.
Rooms were very nice and clean. The only pet peeve we had was that the shower area had only a partial door, so had to stand ion one place to shower, else water would come out. the second one was the very weird sink they had. Not sure if this is a Greek thing, but besides these minor annoying things, the experience was easy 5 star. If you stay in Athens, make this your first choice
