I will start with the positive part of this airbnb experience.Aris was a sociable and comunicative host willing to help by offering all the information that you need like: a video of how to check in,some tips and tricks related to Athens and so on.
On the other side, regarding the apartment I couldn't say that I have a good feedback about it.First of all , my first impresion of it was that is too old and smelly(like cigarrets, dust, old furniture), in the fridge I found the rests from other guests,the kitchen's furniture was sticky, I had to clean the floor because it was dirty and on the ceiling there were spider web.The bathroom was ok, but not enough to cover the other parts. To be honest we preffered to spend our time as much we could outside to avoid to stay there.
Regarding the neighborhood, it wasn t quiet at all as I read in the other comments, a lots of cars with loud music were passing the street, neighbours were screaming and were sleaming the entrance door at 1 am . We couldn t take a proper rest at all and we didn't feel it safe either during night when we came back from the metro station.
Regarding its proximity to the center: it is at 56 minutes away by walk from Acropolis or 15 minutes away by walk from metro station Sepolia,then you have like 7 stations to Acropolis(10-15 minutes).
To sum it up, this was my first negative feedback that I had to give for an airbnb apartment ,but I had to be honest and to let others know my opinion about it and believe me I tried a lot of airbnbs at the same price in a lot of countries until now .I won't recommend this accomodation,sorry.
