We stayed at Eleni's place mid November. We thought it was ideal for three people and felt very comfortable. It's a pretty apartment, too. Very sleek. It's also in a central location in Athens and it takes around five minutes to walk to the nearest supermarket or the metro station just beside it, from which you can travel to any tourist attraction in minutes. We loved that. Traffic noise is a bit bothersome, but Athens isn't the quietest city around, anyway. You could experience the same thing elsewhere. We didn't have a problem sleeping through it. Finally, Eleni was easy to reach and helpful whenever we had something to ask. I wouldn't bother with looking for another place to stay if I visit Athens again.
