La Locanda del Salimbecco, is approx 10min walk from Termini station, we arrived, hot and exhausted, and the staff were more than happy to store our luggage until our room was ready. The staff were very helpful in getting our luggage up to our rooms inspite of how heavy our bags were (thankfully the same service was provided on check out).
A few minor things: the air con temperature was easy to adjust, however the adjustment to set it so it doesn't blow down on you (especially at night) wasn't adjustable.
Although a Bed & Breakfast, they don't provide breakfast on the premises, however, the do have an arrangement with a coffee shop a few doors down. Breakfast was coffee, pastry and juice (normal breakfast for Italians).
Overall I was happy with La Locanda del Salimbecco, and wouldn't have any hesitations in recommending it to others.
