O'Shawn wasn't there when we arrived but it was not a problem as he already provide direction to go to the apartment. Somehow, we missed out the house since it was night and we couldn't see clearly on the apartment number. Have to ask for direction from people around there.
Apartment is close to Arch of Hadrian, Plaka and Syntagma Square.
Only thing is that the water heater need to be on 30-45 mins earlier for the water to be heated up. Kitchen area is a bit cramp but is not an issue.
Overall, it was a great stay. O'shawn is a great host very generous to let us check out late during our stay. Thank you O'Shawn.
