Location: Real close to airport... less than 10 dollars on the taxicab.
The noise level (due to planes taking off) is high initially but we got used to it after a day or so.
The Public transportation is really convenient from this place. Several buses/subways to pick from. We felt safe walking around even after 9 pm searching for souvlaki carts (they have a few in this neighborhood).
Owner: Great communication. Daily email blasts with helpful tips.
The room: a tiny apartment with 3 couches. Clean and organized.
