The hotel is perfectly located between the Pantheon and the Trevi Fountain. The staff is wonderful, the breakfast is excellent, and the rooftop bar offers a truly Roman atmosphere.
The main downside for us was that the hotel is not very baby-friendly in terms of facilities.
There are no high chairs at breakfast, which means you have to hold the baby in your arms the entire meal instead of sitting and eating comfortably.
The hotel is not fully accessible — while there are elevators, there are also steps and different levels between the elevator and the rooms, so they recommend leaving the stroller at the reception.
Going back to breakfast — if I can't bring the stroller upstairs, at least provide a high chair...
Aside from the accessibility issue, the hotel is truly perfect.
