What a cool AirBnB! Theo's place is right in the middle of the action - the Acropolis and the shopping center are both <20min walking distance away. The flat was fairly easy to find (note: we showed up at 11pm). Follow Theo's directions - keep climbing the stairs until you see the yellow line on the ground that leads directly to the flat. Accessing the gate and the flat, itself, were extremely easy. We (2 adults and 2 elementary aged children) loved the flat - it had everything we needed and more. Theo was extremely helpful when we couldn't figure out the heat (we picked a particularly cold set of days to visit), even showing up at the flat to help us out. As other reviewers note: because you are so centrally located, the area stays active well into the night, so bring a white noise machine or earplugs if you're a light sleeper. This said, I had no concerns about safety. Thanks, Theo!!
