Take bus X95 to Syntagma Square. From the bus stop (you 're dropped off to the right of the main square, if facing Parliament) you will go straight a few paces and take a right at Amalias Avenue following it down until you see a massive roman arch on your left. You'll turn right on the cobble stone path that emerges here (D.Aeropagitou) and follow it until the second left, which is Makri street. Go straight down Makri street, on the right you will see the hostel, Makri 12. Alternatively you can take a 4-5 euros taxi ride. (but be careful of cons!). The walk is literally seven minutes. There is no reason a taxi driver should ever charge more than 5 euros, if that. Don't get swindled! help at the hostel if needed.
