Rome is a great city for walking. Public transportation is a dream. We visited for 6 days and could have spent a month. The 3 best experiences I had included an early morning tour of the Sistine Chapel plus a tour of the Vatican Museums, seeing all the random fountains and art at every turn, and trying pizza in a small shop near our AirBnB. Our room was on Via Tiburtino just East of Termini station in Rome.
The only bad experience was minor. Brad and I got separated when boarding the metro on our second or third day. But we were able to reconnect at the destination station. All ended well but it was stressful for a moment.
Overall the beginning of our adventure has been really amazing. I still can’t believe we are doing this.
