This place is just good fun - you enter it through a slightly creepy shopping mall and it's essentially just a renovated building on a roof, but it was one of the best places we've stayed in Greece. The apartment is clean, with everything we needed - and the hot tub with views of the Acropolis (probably the main reason anyone would book this) was a fantastic place to hang out and watch the sun set with some drinks, especially when we figured out you can use the hot tub as a bluetooth speaker!
Super central too, so you can get to most of central Athens with a 10 minute walk or less, but if you're like us you'll be hesitant to leave the apartment and the nice warm tub.
