Great place with everything you might need for a short (or long) trip to Athens. The view from the balcony is great, the bed is comfy, the bathroom area is clean and super modern.
Adonis was a thoughtful and caring host as well. Checking in and checking out was a breeze. My only complaint is that the wifi speed was a bit slow. But if the main purpose of your trip is exploring the city and not work that wouldn't bother you at all.
