Definitely a budget hotel, in a very good location in Omonoia square, few steps from metro.
There is a feeling of a not very secure area at night but it isn't true, Omonoia police station is less than 50 metres away.
It is among the best prices you can find downtown Athens with private facilities. Better avoid the rooms on 1st floor, toilet empty with a pumb which is noisy. For this I asked to change my room which they did immediately, so service was more than fair. Personnel was helpful with couple things I asked.
I would stay again when looking for a single budget option close to center of Athens. There is much space for improvement in common areas of the hotel(lobby, stairs etc)
