We had a great stay at Aris's place and he was a fantastic host. He could come to pick us up at the airport, which was just great.
Yes, less than 30 seconds from metro station !! His apartment is beautiful..even better than the pictures in real, very tastefully done. We closed the apartment in his absence and left the keys...very trusting. He also helped us suggestions for our sightseeing in Athens. We highly recommend a stay with him.
