Excellent location. All the cool shops are nearby. St. Peter 's SquareThe stamp is a 5-minute walk away.
We lived in a chic room with two toilets, a shower and a bathroom (ext in bad weather, you can warm up).
Breakfasts are richer than European. Champagne is served.
In the restaurant in the evening we fell in love with pasta with porcini mushrooms. In season we recommend (not cheap 28€)
