We've stayed for a week and it was absolutley wonderfull.
Livia is a very sweet and kind host and we really recommend this appartment.
At arrival Livia arranged a personal pickup from the airport. Once arrived at the appartment we where stunned by the beautifull view of the Dome of the St. Pietro, but even more by the little paradise of plants in the garden.
The appartment itself is very clean and has everything you require to relax, cook a meal yourself or search a bit of shade during the heat. Most of all it felt like home, with the beautifull wooden furniture and floors.
We also recommend to have lunch or diner in the garden, for it has the perfect temprature and cozines.
A top of that the appartment is close to a busstop (5min. walk) and trainstation (10min. walk) or if you'd prefer to go the by foot, it'll take about 15 min. to St. Pietro and 20 min. to the center.
It's a hidden treasure on Airbnb, so don't look further just book this place :)
