Both Emiliano (Gabriele's partner in Rome) and Gabriele are incredibly helpful hosts.
The B&B is located very close to the Vatican museum and St Peter's Basilica, as well as the metro A line and several busses. This makes it the perfect location for sightseeing, as it's supereasy to get around the city.
The building and rooms are clean, and atmospheric - it gives you the feeling of actually staying IN Rome, rather than visiting Rome. Highly recommended!
