To call this a 4-star hotel is misleading. This is more of a hostel with an upgrade, perhaps a 3-star hotel if we are really pushing it.
The rooms are very small, pretty bare bones, but there is a mini fridge, decent AC, and a small smart TV.
The elevator is also microscopic so you might as well walk.
Breakfast was decent, but you eat outside on a covered patio (rain or shine), so consider time of year (October is comfortable).
Location is central, but Athens is generally a very busy city and this area in particular can feel overwhelming.
