The apartment is in an ideal location and really is lovely in every way. Spotlessly clean, thoughtfully and tastefully appointed, and with a sense of spaciousness and light that the photos can't really communicate. It was easily more than enough space for our family of four, and would have been equally comfortable with more people.
Between the large windows and magnificent terraces with their views of the Largo di Torre Argentina and the Janiculum hill beyond, as a guest you end up with the very definite feeling that you're in Rome and not somewhere else--even when you're lazing around the apartment at day's end.
We've stayed in plenty of Roman apartments, but none better than this one. Very highly recommended.
