The location was great, the place was very clean. I was working 10 days from the apartment as I have a remote contract, and the internet was fast and reliable. The Acropolis is very close by, a couple of minutes walk. There is a very nice salad bar around the corner, and loads of little supermarkets within a couple of minutes walk.
I particularly want to mention the driver Christos, who was very friendly, kind and sympathetic. It made the drive from and to the airport very enjoyable.
