We stayed in one of the new rooms on the first floor which was done to an absolutely beautiful standard, very modern, comfortable and luxurious. The room had a mini fridge, safe box, kettle, air con, bidet and the best shower I've ever used with mist, waterfall and handheld head. The bed was huge and probably the best I've slept on in a hotel.
Breakfast was a huge offering including pastries, fruit, yoghurt, meat, cheese and some cooked elements (eggs, aubergine and, for some reason, chicken nuggets) and somebody attentive was on hand to serve drinks/keep things stocked and tidy. Freshly pressed orange juice was a lovely treat!
When we arrived, the lady on reception annotated a map and recommended some restaurants for us before guiding us to our room. Somebody was on hand if we needed help.
Short 5 min walk from the Trevi fountain, maybe 10 mins to the Pantheon and slightly longer but still manageable to the Colosseum. Vatican city is walkable but the hotel recommended 5 stops on the Metro. If you enjoy weird art made ofdead monk skeletons, you're only 2 mins from the Capuchin Crypt.
If we were to be fussy, & for the sake of a full review, the only 2 things that would've improved our stay was some natural daylight (sadly even with curtains open the window was overlooking a dark area with metal window bars - but in the middle of a city so expected) and the light switches were both numerous and confusing with the electricity card reader lit all night.
