I got upgraded to room 103; a 1st floor room with a front-facing balcony and a view of the Parliament building.
Rooms are modern and well equipped and spacious.
The lobby bar is a bit soulless and really just the place to meet and head somewhere else.
There's a rooftop terrace, but it wasn't in use when I was there, although it offers great angled views of the Parliament, and central Athens. It was a pity, but it was still early in the summer season.
Breakfast is good though. A good buffet selection of both hot English breakfast items, plus cheeses, breads, cereals and cold meats.
