This apartment is highly recommendable! Carla is a great and very friendly host. From the moment we booked (only a few days in advance of arriving), Carla was communicating great with clear instructions on how to get to the apartment and fast replies answering all questions up front. Upon arrival, she was already waiting in the apartment and gave us a good and thorough tour of the place. She really left us with the impression of caring a lot about her guests and we had the feeling we could contact her whenever we needed anything.
The apartment itself has a great layout with a bright and open living room area to the street (with some traffic, but not loud or irritating). The kitchen is well equipped and you could easily cook here, if you want that. The bedroom is to the back, with a large and comfortable bed. The toilet and shower are separate, modern and clean.
The location of the apartment is really great for seeing all the main attractions. You can walk to most places, which we did without any problems. The street itself has some traffic but is quiet compared to other larger streets in the Rome city center. The near surrounding has some small shops and several restaurants, bars and also some supermarkets. Especially a place called "Il Goccetto" just around the corner is a small gem highly recommendable for a few glasses of wine and different Antipasto Misto.
In conclusion, Carla and the apartment is definitely very recommendable for a stay in Rome.
