The location couldn't be better -- it was truly amazing to look out the window each morning and evening at the Pantheon. And despite the constant bustle of the crowds below in Piazza della Rotunda (especially during Capodanno!), the windows/shutters were effective in keeping out the noise at night.
The apartment itself was just as pictured -- modern, spacious, and comfortable. The building elevator was especially convenient with suitcases and for the senior members in our family.
