We have just got back from 4 nights and had a great time. There are pros and cons to our air bnb experience. Lets start with the pros...
Excellent location - 2mins walk to the metro and 20mins to Vatican. Some nice restaurants and supermarket close by but no real bars. Wine was ridiculously cheap!
Facilities - plenty of homely things and resources. Nice shower and great bed. Quaint terrace garden.
Hosts - friendly and helpful with hints and tips.
Cons...
Unfortunately it didn't get off to the best start as we had booked Maria and Stefano to pick us up from the airport but they went to the wrong one and got caught in traffic so we had to wait an hour for them. Took us back fine though.
We were also short of towels and pillows and had to wait until the next evening to get them so they could have been more prepared.
Wi fi is a little temperamental
Walls aren't very soundproof.
No microwave or sofa and chairs were quite flimsy.
Overall though, despite the issues we had a good time and the apartment is good value so would still recommend
