We had a great time at the Peppe house. It was perfectly located, clean, comfortable, and felt just like home for the 8 days we were there. You can get to a main tram by just a block away, and that will help you get anywhere in the city. Giuliano met us there on our first day and let us know all the basic details of the house, local areas to try and was very nice and helpful.
When I return to Rome I would definitely stay at the Peppe house again. Highly recommended for sure. If you get a chance, rent a scooter when there, it was totally awesome and was a great way to see the city and get around fast.
