We have stayed at the apartment during a weekend in Athens with 5 friends. Before our stay, the communication with our host Victoria was very good: she replied quickly to any questions and gave us some advice about places to visit.
The apartment looks as impeccable as on the images. It's spacious, modern and very clean. The shared living room is large enough and very comfortable. There are some nice extra's, such as TV's in every room, a PS4 and a kit to make your own Greek ice coffee.
I do not agree with other reviews stating that the area is unpleasant. Athens looks a bit raw and unpolished in many places, and this street is no exception. I personally think this makes Athens interesting and we never felt unsafe in the neighborhood or anywhere in Athens. Angel's apartment is highly recommended!
