Considerate and attentive hosts. This would be enough in my book, but the apartment is comfortable with all the right amenities--and clean! We travelled with our 18 month old and it worked for him! Also, the apt's location was both convenient and enviable: right across from a mini market & famous bakery, and steps away from the pedestrian path up to the Acropolis and an evening destination with musicians, puppeteers, young and old taking in beautiful Athenian summer nights.
