We stayed in the apartment in Via Nicolo V for 7 nights in May.
The apartments is in a quiet residential area, and is equipped to a high standard. The presence of a garden and gym was an added attraction in our choice. the neighbourhood around the apartment includes shops, supermarkets and a variety of restaurants - all within walking distance. The proximity btw the Vatican means there are some tourists, but in many ways it is a typical Rome residential neighbourhood. The Metro is a 15 minute walk way if you close to use it.
We thoroughly enjoyed our quiet, relaxing stay, with the garden allowing us to enjoy both the Rome sunshine and, one evening, a barbecue. If you wish to be very close to the main tourist sites this apartment may not be for you, but if you want a stay in a typical Rome neighbourhood you will not be disappointed.
