Secret Rooms and Bath of Diana review

My verdict: the lowest-rated of the six listings, at 4.0 from 21 reviews, and the only one that takes you anywhere the standard ticket cannot. Both halves of that sentence are true and I am not going to bury either. Four themed rooms and the Bath of Diana, one to three hours, run by a separate trust on a separate timetable. Expectations decide whether this works for you.
4.0 from 21, and what I think is behind it
This is the weakest score on the site and it is not a large sample. Twenty-one reviews is enough to notice a pattern and not enough to prove one, so what follows is my reading rather than a fact I can hand you.
The Secret Apartments are four rooms and a bathroom. They are not a second gallery. A visitor who books them after reading about four wings of pictures, a 1767 hang and the largest privately owned palace in Rome can walk out in under an hour feeling thinly served by something that was never advertised as long. A 4.0 is exactly what a good short thing sold to people expecting a long thing tends to score. Book it knowing it is a focused look at four rooms and the arithmetic changes.
Why there are no reviewer quotes on this page
Twenty-one people rated this and I have no wording from any of them that I can reproduce. So this page quotes nobody rather than inventing a reviewer or lifting a sentence from a different listing. The one reader verdict I can point you to is on the plain entry ticket review, where a reviewer who had booked the ordinary ticket went out of her way to recommend these rooms.

What is actually behind those doors
Four rooms tied to the elements, plus the bath. The Salotto del Fuoco, with paintings by Pietro Testa, Ludovico Carracci and Massimo Stanzione. The Sala dei bambini, on music and astrology. The Sala degli Amorini, with neoclassical frescoes by Annibale Angelini. And the Bagno di Diana, the Bath of Diana, inspired by Pompeian painting.
None of that is on the standard route. If you have walked the four wings and want to know what the rest of a house like this looks like when it is not hung with four hundred pictures, these rooms are the only published answer. The rooms in full goes further than a review page sensibly can.
The separate-management problem, stated plainly
The Secret Apartments are run by a separate entity, Trust Floridi Doria Pamphilj, and their published opening hours are not the gallery’s. They are listed as open on Wednesday, the one day the gallery itself is shut. That is not a trap, but it is a genuine source of confusion, and it means two things.
First: do not assume a booking here also gets you into the picture galleries, and do not assume the reverse either. Second: treat the hours as something to confirm on the booking screen rather than as a promise you have read on any site, mine included. Two organisations sharing one address will always drift apart on a calendar. The gallery’s own closure day is fixed and well documented; this is the one corner of the building where I would check twice.
What works
- The only listed way into the four element rooms and the Bath of Diana
- Rooms that are not on the standard gallery route at all
- Genuine paintings in them — Testa, Ludovico Carracci, Stanzione
- One to three hours, so it can be fitted around a gallery visit
- Open on days the gallery itself is closed, which can rescue a Wednesday
- A guided look, in rooms that would be unreadable without one
Worth knowing
- 4.0 from 21 reviews is the weakest score of the six listings
- Four rooms and a bath is a short visit, whatever your day has room for
- Run by a separate trust, so hours and conditions are not the gallery’s
- No quotable reviewer wording, so the score is the only reader signal
- It is not a second gallery and should not be booked as one
- Confirm the date and time on the booking screen; the calendars differ
What it opens
- A guided look at the four themed Secret Apartment rooms
- The Bagno di Diana, the Bath of Diana
- Rooms that are not part of the standard gallery route
What to check
- Any assumption that the picture galleries are included — check the option
- The gallery’s own opening calendar, which this does not follow
- A long visit — this is four rooms, not four wings
Book this as a second act rather than a main event. An hour in four rooms lands very differently after you have walked the corridors and understood what kind of house this is. The building itself is the context that makes the Bath of Diana worth the detour.
Who should book it, and who should not
Book it if you have already decided the palazzo interests you as a house and not only as a picture collection. Book it if you are coming back to Rome, or staying long enough that the gallery is not your only visit. Book it if a Wednesday is the only day you have, since its published hours are not the gallery’s.
Do not book it as your introduction to the Doria Pamphilj; start with the plain entry ticket and the four wings. Do not book it expecting volume — it is deliberately small. And if what you want is an evening in the private apartments rather than a daytime look at them, the concert is held in the Princess’s Secret Apartment and is a different proposition altogether.

Frequently asked questions
Why is the Secret Rooms tour rated lower than the other listings?
It carries 4.0 from 21 reviews, the weakest score of the six. My reading is that it is a short, focused look at four rooms and the Bath of Diana, booked by people who expected something the size of the picture galleries. Twenty-one reviews is not enough to prove that. What the rooms actually are.
Are the Secret Apartments included in a normal Doria Pamphilj ticket?
No. They are not on the standard route, and they are managed by a separate entity, Trust Floridi Doria Pamphilj, with opening hours that differ from the gallery’s — including Wednesday, when the gallery is shut. Confirm the date on the booking screen. What a standard ticket covers.
Is the Bath of Diana worth seeing?
If you are interested in the palazzo as a house, yes — it is inspired by Pompeian painting and there is no other published way in. If you came for the pictures, walk the four wings first and decide afterwards. The main route is here.
