The Apartment was really nice and clean, no cockroaches (in the previous older reviews mentioned) . AC in each room, which is especially pleasant in hot Athen. You have everything from toaster to washing machine there, 4 sleeping places.
The district is loud and not that fancy, but it isn’t dangerous there at all. At least we didn’t have any troubles there.
You can get to the Acropolis by public transport in 20 minutes , 40-45 minutes by foot.
The only problem for us was that check-in is only from 3pm to 10pm available, and there is no possibility to get the keys any other time. Our plane got little late and we had to take an expensive taxi from airport, not to stay on the street at night. Fortunately after long negotiations the host told us we can get the keys until 11.30 pm. Otherwise the communication with host was good.
We definitely recommend to stay there if you come to Athens. Price-Quality Ration is on the high level.
