Nassos is a really nice host. unfortunately we didn't get to meet him. the instructions to get to the appartement were really clear . The place is really nice and not far from the metro station Petralona.
unfortunately the bathroom was not really clean because the previous host changed its check out time and so the cleaning lady didn't have the time to clean everything when we arrived ( Nassos sent us a msg to ask us to check in a bit later but we didn't get the msg because we were on a ferry a that time). except that everything was perfect and I'm sure that if we checked in a bit later, it would have been beyond perfection.
We will definitely come back if we visit Athens again.
