Stayed here recently on 2 separate occasions.
This is a new hotel, in a newly built building which opened in late 2020.
There are 7 floors total, including the ground floor.


Positives:

-Hotel is brand new and opened in late 2020.
-Windows CAN be opened for fresh air
-Fancy soap and shampoo (salvatore ferragamo brand)
-5 blocks from the famous street "via veneto".
-Good selection of restaurants in the neighbouring streets.
-Despite being small, this property aspires to the boutique hotel style and is therefore a bit more elegant
-As titanium member got a welcome gift, on both my stays. Once a bottle of champagne, and the 2nd time a bowl of fruit.
-If you don't mind walking 5 blocks, there is a taxi stand at the corner of "via veneto" and "via campania" next to the Marriott Grand Flora hotel. Getting the taxi at this stand will save you some money as taxis in Rome charge extra for the journey to the place where they pick you up.
-This property is significantly cheaper than the other Marriott bonvoy properties in central Rome. Seen nighly rates as low as 100 euro per night. However, I do not think this property is worth more than 180 euro per night due to the small sized rooms.
-All you can eat fixed price Chinese/Japanese/Sushi fusion restaurant called "Komi" very close by on Via Romagna 20

Negatives:

-The hotel is of a small size. Many (but not all) of the rooms feel small and a bit cramped. There are 7 floors including the ground floor. Floors 1 to 4 have 8 rooms each. Floor 5 has 6 rooms (some with balconies) and floor 6 (top floor) has only 3 rooms which I think are the suites.
-There are 2 lifts (elevators) and these are also quite small.
-The distance to the nearest metro station called "BARBERINI" (metro line A) is a good 10 to 15 minute walk. This is fine when LEAVING the hotel as its all downhill, but when ARRIVING this can be quite tiresome walking uphill (even in good weather). However, there is an official taxi stand outside the metro station which can take you uphill to the hotel. Price will be between 4 and 8 euro for the short journey.
-Some of the deluxe rooms on the 5th floor (with balcony) only have bathtubs (not showers) and they have not been built well to keep water from going onto the floor. Not sure why a super modern hotel is still installing bathtubs without walk-in showers in this day and age.
