we really enjoyed our stay at Efi's place. It's perfect for visiting the main attractions of Athens.
We were picked up at the airport by a taxi that was organized by Efi, so getting to the apartment was hassle free. Even more so as there's an elevator which is a great help when travelling with a child and lots of luggage :) There's a supermarket close by and the balcony was nice to enjoy a beer in the evening.
I can totally recommend Efi's place!
