The view is unbelievable from this outstanding location. Just a few blocks from the metro, and an uphill walk so wear good shoes, Xeni's home is more than we expected. The artistic décor is wonderful - and she welcomed us with Greek coffee. We were up at sunrise every day here to watch the view and hear the birds. The area becomes bustling with people off to work and kids to school later in the morning. On Saturday we were able to hear the church bells before we left.
Xeni is an amazing host. She not only welcomes you personally, she provides details of her local favorites. My husband unfortunately lost his wallet on the bus our first day to her place, and she offered to help us with a police report, etc. We wish we had more time to spend exploring Athens. If we ever have the opportunity again we will definitely stay at her home.
One tip: if you are comfortable taking the metro we found this easier than taking the bus to the airport. It will cost about 10 euros per person, but is fairly fast and easy to navigate.
