Costas is a very kind man with a pleasant personality, who was not only typical by showing us just the house but, he was willing to help us from the beginning of our stay and inform us for anything related to our stay in Athens.
The house is in a perfect location downtown Athens and you can go anywhere on foot .
Generally, the house is exactly as comfortable as it looks !
I would recommend it for sure and if I go back to Athens I would definitely choose Costa's house again !
