Luca's apartment is in possibly the best location in Rome. Being near a million restaurants, shopping, and a walking distance from nearly every major landmark, staying here is literally living in the heart of the city.
The apartment is also very clean and well organized with a great view of the square below and a nearly silent bedroom (which also has a great bed).
Word of warning though, the stairs to the apartment are old and steep, so keep this in mind if this may be an issue for you. Otherwise, the place was nearly perfect for our 3 night stay!
