Amazing location! Very centre of Rome and everything easily done by foot. The second you step out in the Piazza there is a great ambience. It's between Trevi and the Pantheon and a million other beautiful spots.
For a couple the room can be tight, but really we spend almost all our time out and about so this is not a problem. The kitchenette is very handy as it means you don't have to eat out for every meal and can make some lunches and dinners at home.
