We were able to travel to Rosa's place from Florence and walked from Roma Termini. I had did have some issues with my phone so I was able to let Rosa know we were delayed but did run into issues letting her know we arrived. Once I was able to use a phone Rosa was very responsive and showed up to let us in immediately. She had a map of Rome and a very informative booklet with her favorite restaurants and gelato shops- we tried several of her recommendations and were not disappointed. This stay was one of the best of our two weeks in Italy. It was very modern and well equipped with great A/C, working elevator, was very clean and well taken care of. Would definitely stay again
