We want to thank Katherina and Maria for the hospitality and help, we had a great time in Athens. The apartment is perfect for traveling with the family, has good air-conditioning, large fridge, all electronic appliances, two balconies. There is a small supermarket just around the corner where you can buy things even on Sunday. Google Maps doesn't show exact time to the metro, it really takes 5 minutes. It is very easy to get to the apartment from the airport by train or metro.
