We had a great stay at Andrea's place! We didn't spend much time at the apartment since we were out exploring, but the apartment is spacious with great natural light and a comfortable living space. The location was great for us - a little quieter than the other side of the bridge, but a 10 minute walk to the Vatican and the Pantheon and half an hour or so to the Colosseum.
Andrea met us at the apartment for an easy check-in and gave us some great restaurant recommendations. We cooked in one day (it was Christmas - most places were closed) and the kitchen was well-stocked.
We would definitely stay here again!
