We stayed in Pantelis' apartment for 5 days during June 2015. His apartment is exactly as it appears in the photos and very spacious, with an amazing view of the Acropolis and Lycabettus hill. The kitchen was great to cook in as it is very well equipped.
Pantelis left detailed written instructions on how to use everything in the apartment which was very helpful. Even though Pantelis was not in Athens at the time as he was away on holiday, he was super helpful over text message. He helped us with organizing a cab to collect us from the Airport on arrival and also take us to our early morning ferry when we left.
The location of the apartment is great; it's a short walk to the Parthenon and surrounding areas and there is a well stocked grocery store nearby.
I definitely recommend the apartment to anyone looking for accommodation in Athens.
