When you need to book a last minute reservation in Athens, especially when traveling on the cheap these guys are a godsend!
First off there are few places you can book at student price where you can wake up to such a good view. This place is in the middle of everything that you want to see. Easy walk to the acropolis, great food markets downstairs. Such a good value.
The best part is that these guys are so flexible! I've stayed many times when I arrive in town and I need a last minute place because their booking fees are so low.
I've also met some great people also staying at the place.
