You cannot find a better place in Athens! My friends arrived before me and Spyros checked them in. He communicated very well via the AirBnb app. While staying there we walked to everything. We walked to the supermarkets, to Temple of Olympian, to the Acropolis, to Hadrian's library, etc. The price from the airport to the airBnb (via Beat taxi service) was 40-55 euros either way. The view was amazing. Watching the sun set on the Acropolis while sitting on a huge terrace was perfect. We used the washing machine and cooked with no problems. The apartment had detergent pods, dishwashing soap, and some essentials for cooking. They have plenty of clothing racks (enough for 2 loads to dry simultaneously) and the clothes were dry in less than 24 hrs. The elevator is small but good enough to get our luggage upstairs.
The only con would have to be the WiFi. It would give us some problems when re-connecting and we would have to reset the router to fix it. We did that about three times during our stay and it wasn't as fast as expected. However, this wasn't a deal breaker for us. Just required a little patience when resetting.
In short, I would gladly return to the apartment upon returning to Athens. It was a pleasure to stay here :)
