I have been using Airbnb for over 5 years for all my personal travels and by far Sabrina is the greatest host I have come across. She's extremely helpful, responsive and helped us with just about anything we needed help with.
The apartment itself was fantastic too. Very comfortable, with lots of space, and all the essentials. Great location, within walking distance from Campo di fiori, Pantheon, and shops.
I highly recommend the apartament and Sabrina as a host and would absolutely stay there again next time I'm in Rome.
