My advice to others is don't let the graffiti in the area scare you. In fact some of the graffiti are art pieces. The place is actually quite safe. (But this I cannot say of the metro stations in Athens where there are full of pick-pocketers) One plus point about Stefenos' place is his fully functioning kitchen where we can prepare some simple home cooked meals. There are also clothes lines to hang your clothes to dry. Very important for people who stay more than a couple of days.
