Location very near the Vatican is convenient. We did not need any public transport as all the sights are within 45 minutes walk... most within 20- 30 minutes. Apartment is spacious, clean and tidy with all the amenities you would need.
Augusta, who is a lovely host, arranged for us to be picked up from the airport, met us on arrival and showed us the apartment. Lots of more reasonably priced (nothing cheap in Rome!!) restaurants and shops very nearby .
Only small criticism not exclusive to this apartment is we would prefer a duvet as opposed to blankets...just feel duvet is more hygienic and comfortable.
One tip...if you are visiting the Basilica go at 7am and miss the long queue and hoards of visitors. It is only 5 minutes walk away.
We recommend staying at this apartment
