The apartment is exactly as advertised. It is large and very nice! We were just a couple and it seemed very big for us. You could easily entertain a lot of people in the apartment and it wouldn't feel small.
The furniture was a bit worn but everything in the apartment was clean and the all the appliances very modern.
The location is very central. As noted in the description you can literally see the pantheon from the balcony. Luckily due to the location of the bedrooms in the back it is nice and quiet at night.
Our favourite part was the amazing balcony, full sun in the morning and a nice cool place to have a glass of wine in the evening. There is also an amazing glassed in hallway that looks into a courtyard, which was a close runner up for favourite feature.
We would definitely recommend this place!
