We loved staying here. Very comfortable bed & pillows; all memory foam I believe. Shower is tiny but works great. We appreciated having a small kitchen for some basic needs. Location is very quiet at night.
Sometimes felt a little far from central, but Rome is a big city, and we found transit made everything very accessible from this AirBNB. It's super easy to get to from the airport using the regional train (not the Leonardo Express), and just 10 mins walk from the Colosseo metro stop - which means it's of course close to the Colosseum itself.
Flavio gave us great restaurant recommendations and met us at the door for check-in. Everything went smoothly, and he's quick to respond to questions. We'd absolutely stay here again.
