First of all, the space is huge! We were blown away with how big the apartment is. We loved having a kitchen with oven and stove. The showers were great and it is so close to restaurants, supermarket and the best gelato place ever!
The apartment is situated really close to the Vatican, and if you like walking, you can easily walk to nose attractions within 30-45 minutes. We preferred this as we got to see more of the city this way.
Only thing I would recommend is having a kettle. But it was a non issue as the coffee shop close to the house was incredible as well :)
