This is an incredible space in a very friendly neighborhood. You're provided snacks, coffee, a shower from the year 3019 and A/C (which was a lifesaver during the heat wave). There's also a grocery store very close by, in case you need a night in.
You're a short walk from the Giardinetti tram line which brings you right to Termini station. From there, all of Rome is easily available to you.
Alessandro & Sandra are wonderful hosts, easily reachable, and full of suggestions for your stay. I won't hesitate to stay here again the next time I'm in Rome.
