Angelo and Pamela were very welcoming and kind to us. They gave us some tips about what to do, where to eat or drink and where to hang out. They even offered us two tickets for a museum in Roma. The appartment is even more beautiful than it appears on the picture, spacious and very well decorated. For the most chilly evenings, you can even lay on the sofa and enjoy Netflix on their big TV !! The only negative point I could tell about is the location of the appartment ; Pigneto is quite far from the historical center (20-25 min) and the transports in Roma are not well served : we payed a great deal in Taxi transports, which are not cheaper than in France.
Anyway, we strongly recommend this appartment and thank the owners for their kindness/availibility :)
