Francesca's apartment is lovely. It is extremely modern and offers three full bedrooms with en-suite bathrooms plus a fourth bathroom for guests. Could not have been a better layout for our three couples traveling together.
The location is great--several blocks from a metro stop, two blocks from the entrance to the Vatican museums and a charming neighborhood. You'll likely need to take the metro or a long walk across the river to the other historic sites in Rome, but we much preferred staying in this more neighborhood-like location. It was much quieter and more enjoyable than the tourist-filled Old Rome. There is also a charming cafe just next door that is open early for coffee and late for a drink.
I would love to have given Francesca five stars, but my only small complaint was that smoking is or at least has been historically allowed in the apartment so there is the lingering smoke smell. It's most prominent in the shared living spaces, and you can mostly keep it out of the bedrooms by keeping the doors shut. If you are sensitive to smoke smell, keep this in mind. Otherwise--everything was fabulous!
