The apartment is very nice and has everything one needs, even for a long stay.
The area is amazing and is close enough to all the major touristic attractions (even a 45-50 min walk to the Vatican is pleasant when you are surrounded by all the beauty of Rome!).
Paola is a great host, easy to communicate with and she even solved (very very quickly) few improvements I have requested!
I would definitely suggest to stay in this apartment!
