Cristina is a very welcoming host. She opened her unique and charming home to us and made us feel comfortable and at home. Her apartment is great... 5 minutes from the Vatican, but really we walked everywhere from her home. Although my husband and I are big walkers.
Nearby there are restaurants, pharmacy, grocery. The location is amazing.
If you are a light sleeper like my husband, bring ear plugs. The narrow streets send noises upward. But we slept happily with our plugs in. ;)
We would gladly recommend anyone to stay with her. She is so great!
