I opted to stay at PAMÉ, a hotel, instead of getting a normal Air BnB and I was really pleased that I made the decision. As well as being reasonably priced, it was really friendly and clean and everything was extremely easy - leaving me more time to enjoy myself for the one night that I was in Athens. It's in a great location, really close to Exarchia Sq, but still on a quiet street. I would definitely recommend PAMÉ.
