Excellent location for a long weekend with three, four people tops.
The apartment has a handy kitchen, a living room, two clean and adequate bathrooms and two bedrooms. Ideal for two couples or some friends.
The location is close to perfect. Every major attraction is in a 3km circle. If you have a car or use a taxi, set the nearby Piazza Farnese as your destination.
The windows are double glass but seeing as you are in the center of the ancient city, there will always be some residual noise coming through. Nothing that bothered us.
Would absolutely book again for small groups.
