Theo is a really great host, and has been most helpful! He provided us with a bunch of great tips, and arranged a quick transfer to and from the airport. The location was ideal for us, as it was next door to the conference we were attending, while being only a short walk (5 min) from the Acropolis and the Plaka neighborhood. The place itself is a bit dark and noisy but otherwise clean and comfy. Good value for your buck if you are staying for a few days.
