Great stay, Athens was a wonderful city to visit! Debbie was very responsive and there is a Vodafone store (SIM card) very close by as well as a bus stop and 2 metro stations are all within walking distance.
!!! FOR AMERICAN TRAVELERS PLEASE READ The locks and elevator work differently than in the states. The elevator doors are not automatic and are push/pull! When you get to your floor push the door to open it, it will save you a lot of stress (We thought we were trapped in the elevator)
The Locks: The first lock to the building requires at most 3 turns away from the door opening (towards the hinge) and then a turn slightly past vertical position ( / ) until you hear a click on the main building door then push and it should open. The key may seem like it's stuck in the door you have when you try to remove it, keep the key HORIZONTAL/Parallel to the ground (---) and then gently pull the key out, it will not come out if it is not in the horizontal position.
For the apartment, locks UNLOCK THE TOP LOCK FIRST, again 3 turns away from opening at most (again horizontal/parallel to ground position to remove the key (---) )
Then UNLOCK THE BOTTOM LOCK SECOND, the same thing 3 turns away from the door opening (towards the hinge/ clockwise) and then another half-turn to get the key in this position ( / ) when you will hear a 'click' then finally push to open the door
