What I can say for Simone appartment? Just Amasing!!! Simone is one of the best hosts on Airbnb. Appartment was perfect. We had everything needed. Location is just 1.2 km from Colloseo-the city center of Rome. The neighborhood is calm. Metro station is just 5 mins walk from the appartment.
I strongly recommend this location if you want to have wonderful and unforgettable vacation in Rome.
