If you have low expectations and want to stay almost in the center of Athens for a very cheap price, this hostel might be OK for you. It is 2 metro stations (or 20 mins walk) north of Syntagma in a run-down area with not very good reputations, better not to go out late in the night, but during the day it is OK. The hostel is on the 5th floor of an old house, with lifts and is very old from inside. Rooms are basic, but OK, bed was good, wi-fi was working. Toilets and shower are shared, but each room has a sink inside. There is a well equipped kitchen with fridge, microwave and appliances. All the premises are very old, but still working. The day receptionist was a very strange person (seemed exactly like a drug dealer), but was surprisingly helpful and spoke decent English. The female manager persuaded me to pay cash, but accepted my credit card in the end. So, if you just want to sleep cheap, it is OK, but do not have high expectations. Single room costs 15 EUR, you cannot expect more for this price.
