We had an amazing time in Rome. It's a very cute flat and close to everything. As everyone mentioned, if ur a little tall, you have to be very careful as the ceiling is really low near the bed and the bathroom.
Our flight got delayed 3 hours and the host was understanding and accommodating. She was also very responsive when I had question. There's information center on the same street, if u need Rome map or to buy Roma pass. Metro is a block away. Lots of Cafe, Markets and restaurants close by. Do the Vatican night tour if it's available.
