Whilst this is clearly no fault of the host's, the surrounding location for this apartment is truly awful. We walked from Omonia metro to the apartment at around 6:30pm. There were large gangs of men, police cars, fights happening, and numerous people passed out unconscious on the floor along the streets to the apartment. We ordered in food as we did not feel safe going out again. It's a real shame and I hope that the area improves, but currently you could book an equally priced and sized Airbnb south of here and be in a safe and friendly neighborhood.
The apartment itself is lovely, well furnished and the host is really easy to contact and helpful.
