Our family of 4 had a quad room. It was very plain, but clean. 4 single beds made up only with sheets as it was very hot when we were there. Blankets and bedspreads were available in the closet. Amenities include good AC, plenty of towels and hot water, TV, mini fridge. The room had a balcony, but no chairs on it. Our room was at the rear of the hotel overlooking a courtyard between buildings and it was very quiet. Shower is a handheld. Typical set up with key going in slot to have electric running only when you are in room. No paper may go in toilet. Has a tiny elevator, so 2 at a time with luggage.
Near Metaxourgio metro station so easy access to the airport, port at Piraeus, and main tourist sites. From the metro station take the street that runs diagonally off the square (Psarron, although it is not marked) for one block then turn right for one block. Look for the Opap(?) gambling shop on the corner; the hotel entrance is halfway up the block from there. It is a little over 1km to Monastiraki from Metaxourgio so it is walkable to the main tourist areas but very hot to do so in the summer.
We had no safety issues and not sure why others thought the area was not safe. We saw one homeless person in the area and a drunk guy whose wife was leading him home, but there wasn't any more graffiti than in the Plaka and we were honestly hassled more by beggars and Rastafarians in Monastiraki than this neighborhood. There is a police station a block from the Metaxourgio metro station so there is a police presence here, although not so obvious as other areas of Athens. We did not travel in the area any later than 10pm so maybe there are only issues in the wee hours? Anyway, we felt perfectly safe. There are a lot of tourist agency shops in the area.
