Carla's place provided a perfect apartment for us. It was spotless, with good beds, lots of hot water, fabulous bathrooms and everything we needed. The apartment was well equiped beyond the basics with adequate toilet paper, soap and shower necessities for those who didn't bring their own, and face cloths (something almost never found in European hotels).
Annalise was so helpful with information about the apartment and the area. An additional bonus was the luggage storage and car service business in the next building. There are many, many good local restuarants within a 2 block radius, several good grocery stores and a bus line close by. The apartment is very well located for touring, within a 20 minute walk to the Forum, Trevi Fountain, Borgehse.
