We had a great stay at Nico and Marina’s place. Very clean, comfortable and really quiet. Easy access to the Vatican and public transit. We prefer to walk and found it a bit tricky to walk into the Trastevere neighborhood or across the river towards the Colosseum - we did take a bus to the Colosseum one day and it was really simple.
Nico and Marina were very welcoming and quick to respond to any questions we had.
It was everything we needed for a home base for sightseeing in Rome for a few days.
