The apartment was exceptionally clean and Giannis answered any questions we had in minutes and was always friendly.
As others mentioned, there is traffic noise, but our visit was in October, so we could close the balcony door to sleep and it was no problem at all. The location is super central, both for subway/tourist attractions/bars/restaurants so we felt it was definitley a good trade off. As a cis-gender hetero couple, we always felt safe and found the neighborhood really interesting - off space art venues, great low key bars and unique ambiant. We would definitley recommend the apartment for anyone not looking for a cookie cutter athens experience and likes incredibly clean apartments :)
