We had a great stay at Parrotshouse! Francesco was wonderful, very quick to answer questions and welcomed us at the appointed time. He also gave us tips on places and neighborhoods of interest.
The house was very clean, well equiped (the AC was a must!) and the wi-fi worked well. We had no problems with street noise at night. There is also a supermarket just around the corner.
We visited several places in Rome, from the Coliseum to the Vatican, and we never used public transport, although there are two metro stations from different lines just a few minutes' walk. Roma-Termini train station is also about a 10-15 minute walk.
Highly recommended!
