Above all this BnB is in a fantastic location. Very close to the Colosseum, Trevi fountain and the roman forum. We even walked to the Vatican and back. Be aware it is a basement flat and therefore can be a bit musky but that isn't a problem unless you are spending too much time at home! The immediate area around the BnB has everything you need a bank, mini market and a very good (and fairly cheap) place to eat.
Would definitely recommend for a stay in Rome!
