It is a great place to stay and cover the old town. Vatican and St Peter is walking distance (12-14 min).
Very nice neighbourhood and the building is quite decent too.
The checkin was very smooth. Our flight reached before time and it was very helpful of Alfonso to allow us an early checkin.
The apartment is very airy and full of sunlight. It has got two proper bedrooms and a separate living room with a good quality sofa. Everything felt quite comfortable and rich.
Overall, we enjoyed our stay very much and would recommend it strongly for future travellers to Rome.
Cheers
