My wife and I stayed at Michela’s place for 6 nights with our 10 month old son and we had a great time. Michela was incredibly quick to answer any questions we had and was very helpful.
We really liked the location! The airBnB was a 5-10 minute walk from the Vatican and was right outside the Ottaviano metro stop. It was a little further away from other big sites (colosseum, Trevi fountain, etc), but all you need to do is hop on the metro and you are there (or go for a good walk).
Overall we had a great time and would definitely come back!
