We stayed at Arianna's place for the first four nights of a tour of Italy and found it to be perfect for our needs. We especially appreciated Arianna accommodating an early check in, and then arranging to have her sister meet us after our flight was delayed by three hours due to weather. She also dropped by later to print out our ticket voucher for our Vatican visit. As there were six of us we filled the entire guest house and made use of the lovely terrace, the cheerful breakfast area, and the very clean and comfortable rooms and bathrooms. The place is in a nice residential area with great pizza, gelatto, grocery and more nearby. Metro is a few minutes away, and you're in central Rome in very little time. We couldn't have asked for a better place to begin our Italian adventure.
