We loved Francesca's place.
Gino (Francesca's brother) greeted us and literally spent more than 30 minutes with us to introduce their place and neighborhood to us. He had everything ready (maps, guides etc) and showed us everything we needed to know about Rome. Was definitely a great experience.
Another huge plus was the location. Super walkable, only minutes to Spanish steps and 10 minutes or so to Trevi. We only took subway once to get to St. Pete.
