Kostas appartment is just fantastic. It's approximately 5mins away from the Larissa station, where you can reach all the central place in 10mins via Metro M2.
Since it is located in the 7th floor, the appartement offers a beautiful view over Athens and the Acropolis. It has two balconies.
Everything was very clean and Kostas was a great host.
Everything was exactly as described on the airbnb page. I'd definitely recommend this appartment and come back there!
