You should book this apartment immediately! Stefano and Raffaella's place is the whole package. It's in the perfect location, it's a beautiful space, and Stefano and Raffaella are gracious hosts. We were able to easily walk everywhere we wanted to go in Rome from the apartment. It's very centrally located but not in an area that felt overwhelmed by tourists. It felt authentic!
Stefano and Raffaella really went above and beyond for us. Stefano was there to greet us at check in and showed us around the apartment. That night, my husband and I mistakenly locked ourselves out of the apartment. It was around 9pm but Stefano came to our rescue in about 20 minutes.
It was really nice to have a kitchen in the apartment. We were there over New Years, so on New Year's Eve, we did a little shopping at Campo de' Fiori market (also walking distance) so we'd have food for the next day. It was really lovely to be able to do that. We enjoyed sitting at the dining table and looking out at the view of Rome.
One thing I would note is that this place is a good spot if you are on an extended trip. The apartment is equipped with a washer/dryer, so you can do a load or two if you need to. It was the perfect space for two people, but there is a rollout couch, so I think you could fit two others if you wanted to. But we were very happy just the two of us.
I know we will come back to Rome. Hopefully soon! And we would absolutely stay here again!
