BdB Luxury Rooms Navona in Rome is worth it because of the location.
From the BdB you can really reach the most important monuments in town just walking for few hundred meters (piazza Navona, Castel Sant'Angelo, Pantheon and Basilica di San Pietro are so close you can reach them walking in few minutes, for instance).
Furthermore, BdB is located in a little street along via de' coronari (Rome's antiques street), and this guarantees silence at any time staying in your room.
Rooms are small, but BdB had a really good architect able to wisely manage the available space, so that any room has exactly what you need to rest and bath (with furniture, linen and bath absolutely new and clean).
If I can dare giving an advise to people interested in staying in Rome, go to BdB Luxury Rooms. You'll be happy to LIVE the town being part of it.
Have a good stay!
