Amazing location. We walked to the colosseum in the east, Vatican City in the west, the theatre in the north and to the pantheon which is about 2 minutes away!
The room is "cosy" but for the money you can't knock it. Two little side notes. The apartment is up quite a steep, winding and narrow staircase. It's a little difficult with a heavy case. The second is that the bed is a sofa bed. Not a problem for a night or two but longer may be an issue.
