It's a bit difficult to review this place in usual terms of quality/value and facilities discussion. You would want to talk about emotions.

Neither photos could describe the feelings you enjoy drinking coffee on the sunset or exploring the seaside panorama. Moreover, the house keeps the spirit of its first owner who seems to have been a really interesting person.

As for facilities - they are as described, no need to worry. Ed is always in touch and the owners have very useful house-guide.

The only point I would want to add is the transport: the place is definitely designed to be run by a person with a car. Please note. Though we managed to live a week without it with no considerable inconveniences :)
Kokkino Chorio is a very quite Greek village without the sea-beach and with just a basic taverna. So you would want to go down to Plaka or Alymerida. It's a 20-30 min walk down. And to get back they have a descent local taxi service at Alymerida (9 Euros from Alymerida to the place). But if you are going to travel a bit better consider а car rent.

In general - it is like a thing AirBnB was invented for - people happy to see you as a guest in their homes. Please respect the house and the owners!
