Dimitris' apartment is located in Athens' anarchist district Exarchia. As an epicenter of demonstrations in the city, Exarchia got a bad reputation. But don't be alarmed - it is a perfectly safe neighborhood. It has a significant offer of restaurants with delicious greek food, and it will take you c. 30-40min to Acropolis by foot.
The apartment is newly refurbished and sparkling clean, and the kitchen has some basic equipment. Just do consider that the apartment is on -1 level, so you won't get much of a view.
Communication with Dimitris was really effortless, and I would definitively recommend him as a host!
