Good stuff: Loved the location and the features of the property. It's located in a very walkable area with great shopping and dining options nearby. Check in was a breeze. The style of the decor was great and the roof top patio was a great place to spend the evening. Very nice bathroom and a reasonably well appointed kitchen.
Not as good:
Weird layout for a family. There's just three interconnected rooms, so if it's set up for more than two sleeping, you lose any comfortable gathering space.
There was some dust and hairs in the corners, suggesting a lack of attention to detail in cleaning, though our beds and the bathroom were cleaned well.
Appliances in the kitchen were either slightly broken or non functional, and in one case used a UK plug (thankfully we had an adapter). It would be better to not have these at all rather than provide broken appliances.
All in all, we had a fine stay, but if we return to Athens we'd probably look elsewhere.
