We stayed (2 adults and 2 teenagers) at Manuela apartment for 8 days in october. It is a great location, very central, you are near the major sites. The neighbourhood is very safe with a lot of restaurants and bars.
The aparment is like the pictures, spacious, clean and confortable. The wifi is fast. The only negative point was that you are very central so one bedroom is a little noisy.
Manuela was not there when we arrived but there was her son. She was always receptive when we asked something.
It was a very pleasant stay in Rome.
