My friend and I spent 3 nights at Suite il Bollo and would go back in a heartbeat. Barbara and Fabio are absolutely delightful hosts who communicated freely both before and during our stay.
The apartment is spotlessly clean and located a mere 2 minutes walk from Campo di Fiori making it possible to fully explore Rome on foot.
They also provide a portable Wi-fi modem which guests are able to use outside the apartment.
I would have no hesitation in recommending this apartment to others.
