Mario’s studio apartmant is one of my favorit airbnbs (and I have been using airbnbs for years). Highly recommended!
This apartment is just really better than avarage and has many nice touches especially in regard quality (bathroom quality, furnitures, kitchen…)
Transportation to the Vatican is great: one bus that you can get on right az the corner…
The owner, Marios is responsive and flexible.
The street has shops, pharmacy, cafe bars.
