My parents stayed in the Blu Tango Guesthouse (i booked for them on this account).
They had a very good stay in the guesthouse, Fausto gave them a very gentle welcome and gave all the information they needed.
The guesthouse has a very good bed, a nice bathroom and everything was clean and comfortable. The breakfast across the street is delicious. All major sight are in walking distance and the Monti district is a very nice place to stay.
Because of the hospitality of Fausto their stay in Rome was very special!!
