There are three rooms open to tourists, only accessible if tickets are booked in advance with a guided tour.
These rooms are Very authentic and have beautiful ceiling paintings by Guercino .
However , the visit is overpriced as Euro 25.00 is a lot to see only 3 rooms. The famous frescoe by Caravaggio cannot be seen, neither the first floor or the famous staircase.
The rooms are still worth a visit if you are interested in the style of residences of renaissance and papal history.
