I stayed for 3 weeks and had an amazing stay. The area is very safe, it has cafes and restaurants nearby. You can walk to the center of Athens very easily, but if not, it is very close to Metro stations.
Eirini is a wonderful host, always offering her assistance, gives great tips, responds very quickly, and is just such a kind person that I was lucky to encounter during my travels. I felt right at home, I loved my stay in Athens.
