The place was pleasant and George was very kind and helpful but I found the apartment pretty soulless, dark, and quiet. As a solo female traveller, I didn't necessarily feel unsafe, but I didn't feel super comfortable coming back there at the end of the night.
If you need a basic place to stay or have a partner or friend with you then I think this place would be totally fine. If you don't plan on spending your entire day out in Athens, then I would probably recommend staying somewhere more comfortable, with more light and character.
BYO shampoo, conditioner, and body wash - there's just generic hand soap in the shower.
