This flat is well equipped for a short stay, with all the essentials to whip up basic meals and located very close to a Metro stop, a grocery store, and several restaurants (I recommend the gyro place just down the steps!) . The AC was a lifesaver in the heat wave, and was strong enough to battle the high temps with ease! The twin balconies are a wonderful place to spend an evening, or hang your laundry as you leave for the day and it'll be dry by sundown.
Orestis was very easy to get in touch with, and you could tell the great care that he put into this place.
If/when I return to Athens, this will be the first place I'll check!
