I spent five nights in Rossella's B&B and I really felt just like at home.
The appartment is very well located, within wakin distance to Vatican Museums (10') and Saint Peter Square (15'), and just 5' walk from metro.
The appartment is very clean and confortable. The room and the bathroom (for private use) is large, well furnished and spotless.
Rossella is very welcoming and it was nice to discuss with her.
And Luna (the house dog) is very quiet and friendly.
