Stayed at here for 2 nights back in October. I will echo a lot of fransknorge's comments with it being in a good location (walkable to tourist sites, bus stop, and Termini train/metro station) with a nice neighborhood, plus I second the recommendation to the Gelateria SM Maggiore shop, and can recommend the laundromat (Lavanderia Wash Point) across the street from it.

I was not upgraded as a Gold member from my base level room. The cookie was different from what I was used to in other Doubletree stays (dark brown chocolate dough with white chocolate chip bits) but I like the fact they changed it up and it was still tasty overall. During my stay I did notice a tour bus parked outside the front, and the nice front desk agent did say that business was doing well at that point (I think the hotel only opened in April 2021?). It's a modern hotel and furnished nicely but I can't understand the philosophy/line of thought the interior designer was using. Lots of plants and furniture in the lobby made it feel a bit cluttered and lots of tans/browns on the walls and flooring- try to bring a sense that one is outside with nature? Also not sure what they were going for with the TV in the room being hung with leather straps or the choice of the lamp/furniture fixtures with the thin painted metal bars. Is there a "modern/chic" side of Italia here that I am not aware of? Service was good overall, but avoid the bar. The fact that it was a rooftop bar was nice but the layout of the outside patio area is rather narrow with at best okay views, but the service was unacceptably slow. It took an hour just for one overpriced drink (16 or 22 EUR, can't remember) and some cheap dry canapes and it was not like they were busy, maybe at most 2 tables and max 10 guests.

Overall, a good solid choice, and reasonably priced too for what it is (60000 HHonors points or 216 EUR per night were the rates when I booked). Also stayed at the Curio Collection hotel, will have a post in that topic with my thoughts.
