We only had the pleasure of staying two nights at Paola's place- but they will not be forgotten. Paola was very gracious with the check in time- we ran into a bit of trouble using public transit to get to the place from the airport and ended up arriving a lot later than expected. She provided pretty much everything we needed and even got a ride to the train on our way out!
The space is a lot bigger than shown in the pictures with some lovely tall ceilings. The location is a little far from the top Roman tourist spots but there is a bus stop right across the street which can take you right where you need.
