We had a great stay at Lorenzo's place in Prati. His apartment was stylishly appointed and very comfortable for two people to stay in. Kitchen was perfect for preparing light meals and eating breakfast during our stay. Grocery store is just a few blocks away, making it easy to run there for any food / drinks.
This place is fairly easily accessible by public transportation. Walk to Ottaviano metro station is about 10 min and from there you can easily get to Termini and beyond for the 1.50 euro fare. Prati is a charming neighborhood with many little cafes and some good shopping options. It is also walkable to many sights such as the Vatican.
Checkin was easy and efficient. Lorenzo lives just down the block, so when we arrived we just sent him a message through airbnb and he was over within 2 minutes. Checkout was easy as well, and Lorenzo was flexible and accommodating.
If we were to stay in Rome again we would certainly prefer to stay here over a hotel.
