I had a great stay at Panagiotas house. Its very central, and in walking distance of almost every attraction in Athens. The house itself was under renovation when i was there, and could use a little more wolk.
Panagiota is a very friendly woman, who helped me plan my trips around the city. Be aware, that Pangiota has a dog, and that she smokes alot (which lots og greeks do). But she won't mind to stop smoking, if you politly ask her to.
All in all, it was a great stay, a great location, and a very friendly host.
