I stayed at this hotel in mid-May (room 425) and left unhappy with the experience. On the plus side we enjoyed a decent late meal from room service having arrived late on the first evening and we found the guy who served the food pleasant and welcoming.
On the minus side there were a number of things which left us disappointed (i) our room was damned small and in no way resembled the photos posted on the hotel's own website (our room was tired and old in comparison); (ii) small thing but annoying - our bed had only one thin pillow per person when we got there and I had to call housekeeping for extras - I really would not expect to have to do that in a 300 Euro+ a night hotel; (iii) the swimming pool (a big selling point when booking) was closed until June (why? - the weather was glorious); (iv) the costs of PPV films and Wifi are comically high (22 Euros to watch a film, 17 Euros for 24 hours of wifi access - ludicrous both); and (v) the staff at the front desk and the door were consistently unwelcoming (particularly the older guy on the front desk who could barely manage to speak to us). At no point did we feel like we were getting the sort of service we had paid for.
To me the guest directory best summed up the experience - there isn't room for a section entitled "housekeeping" or a number to call for such issues but there is a detailed section informing you of the hotel's dresscode for the various public areas. I have stayed in a good number of hotels over the years which are, like this, branded as 5 star and in the main have had a great time - this is a sad exception and I would not recommend a stay.

We stayed only two nights prior to returning to the US...we wish we had stayed longer...te Aldrovandi Palace was truly a 'surprise' find in Rome. This Hotel is located in a wonderfully serene & safe area with private residences surrounding it. The garden & pool areas are the perfect place to relax and savor the ambiance. The common areas, hallways, etc are all elegantly furnished. From the moment we arrived, we were treated like Royalty...the staff went out of their way to make us feel special & to cater to our every whim. My only regret is that we did not dine in the Hotel's Michelin-star restaurant.closed one day (Monday) and we dined elsewhere the night before we left. I do agree w/a previous comment that the complimentary Van to the Spanish Steps ceases to run too early in the evening...perhaps this will change. Other than that, this is truly a Hotel to enjoy & be pampered at.
We are planning our next visit to Rome in June '09...we would definitely enjoy staying here again...Joanne

In this hotel everything seems to be perfect - very clean - very kind staff - very good breakfast (breakfast waiters are are kind and helpful)

First the plus: Great front desk and portier and bar staffs, nice and big suites (Suite 416 is great for its quietness)

But numerous strong minus:
1) I still don"t get why I had to pay 35c/min for the use of Internet in the biz center + 35cts for every page printed,
2) Room service: I paid 40€ for one piece of veal + fries for my 2-year old daughter (including 15€. for the fries instead of the regular vegetables). As they don't have any child menus, you have to choose from the adults plates with no chopped steak + fries for the children
3) Room service again: One of the smallest choices I got from a 5-star hotel and don't try to ask for the Michelin-star Baby restaurant menu, they will say "No Sir no room service for this cuisine"... Totally snobish
4) When I order for some 100s of €uros, I really hate it when someone asks me if I kept a spoon, like"Are you a thief or what?"
5) The shuttle which is supposed to come and go to the Piazza di Spagna. Fully booked often or just not working until 6.25PM on week-ends. Alright, the hotel is aware of that so they offer you to ask a receipt from the cab and that will taken into account in your bill. But still, it [---]!
Not very strong minus indeed but enough to make me wonder why I spent my money in a place where I had not much consideration.

Finally the location: well, plus and minus. Far from the noise but also far from all of the interesting parts.

Sorry, but next time I will definitely stay at the Hassler or the Inn at the Roman Forum
