Wonderful location, easy to reach from Termini by Metro then a 3 minute walk from San Giovanni metro station. It's also a relatively straight forward 20 min walk to the colosseum with restaurants along the way.
Check in was straight forward, greeted by the host promptly at the time agreed and house rules and info very clear.
Everything was spotless upon arrival and enough supplies for the first day or two. Plenty of space for 3 friends staying.
Would definitely recommend for anyone wanting a convenient base for Rome, and would return again myself.
