Willian was really responsive and communicated well before and during our stay.
His flatmate, George, greeted us kindly even though we arrived really late in the night. (Thanks, George, you were a wonderful host!!)
The room: Clean, comfortable, enough space for two and luggage. There is a terrace you can sit on and enjoy an excellent view of Acropolis. Exactly as described in the posting.
The apartment: Quiet location, near metro (5 mins-ish), the common areas are clean and updated and the shared bathroom is cleaned daily (a plus!), there is a small elevator enough for two (without luggage) or one person (with checked luggage...can probably fit more if your bags are small).
Their cats were sooo sweet and friendly. Even though my boyfriend is allergic to cats, he barely felt the normal effects he does when he is near them. You won't see any cat hair and the litter box is out on a separate interior terrace area.
Would strongly recommend to friends!!
