Location, location, location. Katerina's place has a great location and I always stay on this street when in Athens. Big wrap around balcony and plenty of space. The floor on the Dining room needs to be repaired (could be a problem for less able bodied people) but it is obvious and marked out as an issue.
Overall the place is excellent valur for money considereing the price.
Katerina was very accomodating and even allowed me to stay intil 13:00 as my flight is late.
