My parents lived for almost 2 weeks at Elias house. It is really clean, with everything you need, and Elias / his mother are always here for helping you. It is also possible to live there if you don't talk english (even if it is more difficult, people are nice in this area).
There is noise during summer until late evening so be aware about it if you are easy to wake up, and a shisha bar is at the first floor of the housing so if you open the windows smoke can enter.
It is a really nice place, typical mediteranean area with little shops, restaurants, and at 30-40min by foot to syntagma place.
