For a hostel price this is a good deal. The blue room is spacious, quiet and has a balcony. Like for all shared bathrooms situations you can have good or bad luck. We didn't use the kitchen, but it seemed clean. Metro and bus station are close. The apartment is in Kypseli, which has actually a lot of nice, hipstery parts. I can highly recommend Platia Agiou Georgiou (very close!) and Fokionos Negri, there you can find a lot of bars, Cafes and nice restaurants. Especially in the evening a lot of young people hang out there and these areas seem kind of safe for Athens. The Western side streets of the main street seem to be the unsafe parts (but nothing happened to us there).
