We arrived very late and Giulia was pleasantly accommodating. Her sister checked us in quickly. The apartment is just as pictured - very large, comfortable and decorated tastefully. As a family of 5 adults, we loved having the extra space and not tripping over each other. The beds were comfortable, the kitchen spacious and the air conditioning worked great (especially since it was a hot week when we were there).
Giulia was super responsive when we had simple questions and she also arranged transportation to the airport for us (at a better value than we could get using Uber).
Regarding location.... it is right next to the train station which was great. But, we spent a lot of time 1-2 miles away when visiting tourist spots. The good news, we averaged about 7 miles walking per day. The not so good news is that it was a super hot week, and when returning each night, we were tired, hot and sweaty. Maybe next time we would choose a location closer to the Jewish Ghetto by the river. Tough to know if we would get a place as large and nice for the same price in a different location though. No complaints, just something to consider. We did use the metro to see the Vatican (easy to get to) and we saw public transportation but wasn't sure how to use it (cable cars? and buses). We probably should've asked Giulia bc she was super helpful with other questions. We used Uber one night which was also easy, but mostly we walked, and walked and walked. Good for us because we ate so much pasta and gelato, we needed to counteract the eating somehow!
