Night staff and cleaners are extremely rude, and the cleaners speak no english so its extremely difficult to communicate with them if you need anything. One of the night staff in particular, an older man, his behaviour was disgusting, the way he was speaking to us and shouting at us when we arrived at 2am, and he told us our room was cancelled and nearly kicked us out of the hotel whilst they had charged us in full for the 3 nights. Rooms are quite outdated and old, breakfast is not worth paying for to be honest, as there are barely anything there and also juice taste like water, but you get what you pay for i guess. If your on a budget and don't mind staying in a rough area of Athens, then this is OK, otherwise if staying with kids especially i would not recommend this hotel at all.
having said this, 2 of the guys in reception during the day were quite friendly and went out of their way to make things comfortable for us, bringing us pillows to our rooms, as their pillows are like sleeping on stones. would not return as there are better hotels in safer areas of Athens, which we figured out afterwards unfortunately.
