A four star hotel, this isn't, but Palazzo Olivia couldn't be more in the center of Rome if it tried. Piazza Navona, Campo Fiori, the Pantheon and Largo Argentina are in the surrounding area. The little street behind Palazzo Olivia is full of shops, restaurants and gelato places.
My room in the Palazzo itself was fine, it had two beds, which they push together for couples. The only quirks were that it was a little dark in the room, even after they replaced a bulb or two, and the beds have just a loose duvet on top, not tucked in or anything, which means your duvet tend to slide off in the night.
Palazzo Olivia works best for people who are looking for comfort over glamour. There's a fine little elevator so no dragging suitcases up the stairs, and the entrance is on a very small street, nearly an alleyway, which was a bit off putting at first, but that means the street noise is minimal. In Rome, that's big. I was there for a week, and I found it to be entirely satisfactory as a base.
The staff were exceedingly helpful and gracious, setting up my transfer to the airport and addressing a few small problems with the room promptly.
