We had a great stay in Simonetta's place. Simonetta is a lovely host with great attention to her guests.The apartment is neat and tidy with everything you would need and some extra touches. The bed is great.
The location in Trastevere is perfect, not in the main touristic streets so you avoid the big noses but close to all the restaurants. There are really great restaurants and pizza places nearby. You can also go to the city center by foot or take the tram.
Overall, I recommend this apartment for every traveler looking for a place in Rome
