Roberta's apartment was absolutely perfect for me and my husband. We were in Rome for three nights, we were able to walk to Roberta's place from the train station (Roma Termini) it's only about a mile, you can easily get a bus, uber, or taxi as well if you prefer.
Her home has two rooms, both with private bathrooms. Our room has been recently renovated and it is very nice! It was clean and modern and spacious. There were people staying in the other room and we hardly even noticed! The only shared space is the kitchen and balcony, which are very nice. The kitchen has all the amenities you could want and Roberta provided continental breakfast every morning!
The locating is very nice, especially if you are willing to utilize public transport, which is very easy if you get the Roma Pass. The Roma Pass allows you to use all public transport for free for the duration of your stay of either 48 or 72 hours. My husband and I were able to get everywhere easily that way.
I highly recommend Roberta's place to anyone!
