Wow. Location, location, location.
Exit the building and look to your right and you see Castel Sant'Angelo no less than 100meters from the door, and a 5min walk to the Vatican was incredible. Plenty of cafes and restaurants within steps of Luca's place. It's on the 2nd floor, and the building has a working elevator. Security was top notch too.
The space in the AirBnB comfortable accommodates 4 and the A/C blows cold for both sleeping locations. WiFi only works in the loft room, but since the two couches and table accommodates the space it was not an issue. Would recommend this place and Luca as a host who was incredibly responsive. Clean place as well. The shower takes a second to get used to, but you'll get the hang of it. Stay here and you won't regret it.
