Excellent location, you are a very short walk away from the Acropolis for site seeing, and the Plaka area for bars, shops, and food. No issues with the room size, the view was amazing and our rep Vicky was very helpful.
One issue, most of the dining chairs were broken, so if you have a group of 4 or more then you wont be able to all sit at the table.
The bigger issue is that there are quite a bit of stairs to get to the room, and the elevator stopped working after the first day. We had a fair bit of luggage and also some elder folks with us that made this quite a problem; so be careful if you need an elevator because this one was not dependable.
