I stayed in Rome with my partner and our little son for 4 days. Sabrina was a great host, she made our stay much easier and pleasent. We found a travel cot, perfectly clean and ready to use for our son and some cute toys, that he loved. Sabrina was very helpful and answered to all our questions within a couple of minutes.
The flat is very sunny and warm. The kitchen is well equipped for those who preffer eating indoors. Upstairs there's a huge terrace with a nice view, perfect place for a cup of coffee and a book.
Near Sabrina's place there are plenty of supermarkets, and some restaurants, which are not bad. The centre of Trastevere is just 15-20' away, where you can find a bunch of nice places to eat and have a glass of wine or two. We used a lot the public trasport, as tram and busses - google maps are quite usefull in that case.
I wouldn't doubt where to stay next time when in Rome.
