Rosalba's place is quaint and a great base to travel from. There are buses and the metro very close. There's a great gelato place nearby and there are lots of restaurants within walking distance.
The place itself has a little garden and a nice kitchen. It is a sub-level flat that is right beside Rosalba's place, so she is generally only a knock away if you need help.
It depends on what you want but for me, my wife, and young kid it was a good place to travel from.
