The primary virtue of the Holiday Inn, from my point of view, is that it is clean, comfortable, and in easy walking distance of the bus & train station, even with some luggage. I usually stay there when in transit between Athens and places to the north.
This time, when I inquired about leaving my luggage for a couple of hours after checkout, I was allowed to keep the room until 2 pm without charge; this was extremely helpful, as I was catching a bus ca. 3 pm.
