I think some people might rate this place lower than I did. But as a solo male traveler, I don't need much. This place served my minimal needs.
Some things worth noting that I did not know ahead of time:
This hotel is in a somewhat run down part of town. Lots of graffiti, beggars and metal bars on shops. I asked the front desk attendant about my boundary conditions and he said after dark, on the nonmajor side streets maybe it is not so safe but during the day, main streets it is fine.
I never had any trouble, but I followed his advice.
It is a very short walk to the metro subway station at the Omonia square so very convenient. However, outside of the square, there are very few restaurant or bar type resources. But, only a couple of metro stops to Syntagma square where there are many options and a connection to the airport and one more stop to Acropolis station where the Acopolis, Agora, the Agora Museum, Acopolis Museum and National Archaeological Museums are.
