Alius is a simple, no-frills hotel located near (but not right next to) attractions like the Colosseum, the Forum, Palatine Hill, and (in the other direction) Trevi Fountain and Pantheon. It's on a fairly busy street. The hotel is one of several businesses in an old office building, with lots of marble and dark wood. There is a small elevator. Rooms are small -- I thought ours was taller than it was wide -- but well-maintained. The staff are friendly and helpful. I thought it was good value for money. If you are looking for a luxury experience, this isn't it, but if you want a friendly, well-located place to lay your head, it's worth considering.
