This neighborhood is under going gentrification. In my opinion it has a ways to go. Upon arrival my first question to my taxi driver was “is this a safe neighborhood ?” Full disclosure here, I am a solo 71 year old traveler. I did not feel threatened at any time however, Athens is a huge city with many better options for someone of this demographic. The “flat” is what I would call bare bones with minimal ambiance. The acropolis and other tourist type locations are all around a 30 minute walk.
