First let me say that I lived in Rome while I was completing university so I knew what I was looking for when I searched for airbnbs for a vacation with my cousins.
Francesca's apartment delivered on everything I was looking for and more. LOCATION! I cannot stress how amazing the location is. Trastevere is wonderful for restaurants and night life and is very convenient for getting to all the major Rome attractions. Everything was within walking distance for our group of four since we don't mind walking. Ex. 15 minute walk to Largo Argentina at a reasonable pace. It is also close to the tram if you do not want to walk and a taxi stand for those early mornings when you want to try and beat the lines at the Coliseum or the Vatican. The apartment was clean and spacious and good for our group of four. The kitchen was nice with all the necessary pots, pans, etc to cook meals. We used it primarily for breakfast. The bathrooms were nice as well but only one has a true stand up shower. The other was a tub with a shower head on a cord you had to hold instead of standing under it. Be careful when you use this shower because there is no shower curtain so you run the risk of soaking the floor if you are not careful! The internet was fast but got slowed down by all the devices we had connected to it. (Nerd Family = lots of tablets, phones and laptops).
Francesca was great at communicating with us and even came by to let me and one of my cousins in when we left our keys in the apartment the day the rest of our group was doing a day trip outside of the city. I cannot say how nice this was since other times I have stayed in an Airbnb the hosts were not nearly so accommodating and kind.
I would definitely recommend staying here based on how wonderful the host is and the excellent location and amenities in the apartment. Hopefully the apartment is available the next time I vacation in Rome with family.
PS. Like many others have mentioned the airport transfer that Francesca can arrange is very convenient and is a great value compared to taking a taxi especially when you split the cost between a group.
