Great location and space for the 2 of us. We never used the loft bedroom and would consider that only available for the more agile travelers.
The kitchenette is just as pictured; i.e. a kitchen-in-a-cabinet, but certainly workable. It has a 2 burner induction stove, small refrigerator/freezer and sink.
The grocery store is less than a block away amid a lot of high-end shopping.
We were able to get around to all of the usual tourist spots either on foot (Vatican) or via underground/foot. Underground station is just a few blocks away.
