If you want a good value then this was a nice Airbnb. Clean and comfortable. The area is relatively safe, just full of graffiti like all of athens.
It IS a bit far from everything central but you can have a nice 30 min walk from the place to the Acropolis. Areas like Koukaki and Plaka are also within a 20-30 min walk. The metro is less than a 10 min walk away as well and there are small cafes and restaurants nearby.
