Costanza is a great hostess. The location is optimal for travelers like me. It's 10 min from the termini station. This is nice for easy access to the train to/from the airport. Easy train access is also great if you want to jump on a train and head to Venice, Florence, or the Amalfi coast for the day. And it's not right next to the major attractions, but its only a 15/20 min walk to many of them, and to really get a feel for the city, you should see it on foot. The neighborhood is quite, if you want to sleep in after a night out in Roma. Great location, great hostess, great room!
