Well what can we say..our 'deluxe' room was v. average, the bathroom was tiny and there were chips in the bath...if this is a 5 star deluxe hotel I dread to see the standard of lesser graded hotels...
The minibar had half eaten bars of chocolate and already opened bottles...
The only good point concerning the hotel is the location...right next to the metro and in a great spot for restaurants / sights.

Our 6 night stay at the Bernini Bristol was great. I had read some less than stellar reviews on this site, so I thought I would speak up for the hotel. Its location is ideal for those who plan to travel throughout the city like my wife and I did. Steps away from the metro, internet cafe, walkable to churches, museums, restaurants - you name it. The breakfast is fantastic and was included in the hotel price, it was also a full "American" breakfast that even included champagne. The rooms, while not glamorous, were surprisingly large. The bathroom was very spacious as well. The construction that was going on to the facade did not in any way interfere with our stay. The roof top restaurant is pricey, but the staff are courteous and flexible. The food was good and the views were great. The exercise room is very small, but has good equipment. Fortunately, when I was using it no one else was so the lack of much equipment wasn't a big deal. I would recommend they add some more aerobic equipment. We plan to stay there again when we visit in 2 years.

Stayed at the Bernini for 4 nights over the easter weekend. A fabulous choice. Central location, very comfortable accommodation although room was on small side it had huge bathroom and a balcony overlooking the Bernini fountain. Fabulous views to St Peter's from the rooftop bar. Breakfast extensive and saw us through until tea time! Service was efficient. Plan to go back in October when I take my mother to see the Sistine Chapel.

My wife and I spent three nights of our honeymoon at the Bernini Bristol, and found nothing but the warmest service. The location is good if you want high-end shopping and the Spanish Steps, not as good if you prefer more quaint neighborhoods like Trastevere or Campo De Fiori. Extra bonus for Dan Brown fans - the hotel is right by one of the major locations in Angels and Demons, and not far from Santa Maria di Popolo.
The hotel staff was very welcoming, and the decor is beautiful. The rooms are not luxurious, but are extremely comfortable. We prefer the neighborhoods further south, but if you want something near the Via Veneto and the Spanish Steps, you can't go wrong with Bernini Bristol.
