I would absolutely recommend Flavia to anyone visiting Rome. The location is amazing and so are the accommodations. Even though Flavia wasn't there to greet my mother and I, her younger brother and mother made sure to welcome us and help with settling in.
The room was basically a hotel room but more cozy and comfortable. There were also croissants, coffee, tea, and a mini fridge for us.
Everything was great! It was like staying at a much homier hotel than we could ever find in such an amazing location, a block or two from the Pantheon and from Palazzo Navona.
