The car parking spot it right next to the apartment (not in the same building, but immediately adjacent). There are a few steps to traverse (6 of them to be exact) in order to get to this ground floor, beautiful apartment. It was exactly as described, and in a wonderful location - away from the major tourist hustle, but close enough to walk to the Vatican and the Metro.
Michele was awesome. He ensured we knew how to unlock the door before he left us, since it has a little trick to it, and was so communicative.
Definitely recommend!
