I had a lovely time staying here. Eugenia was there to meet me at check-in, and explained everything that I needed to know. When I had a query the hosts were quick to respond in a helpful manner. I was able to leave my luggage after I checked out on the last day, which was very useful, and there was no issue or delay in collecting it.
Everywhere was very clean, and my room was comfortable. The balcony area was a nice touch, perfect for having a coffee and relaxing a little - weather permitting!
For me, as a solo female traveller, the location, near Metro stop Cipro, was perfect. Very convenient, only about 10 min from Termini (NOTE: at the moment, stations Repubblica, Barberini and Spagna on Metro line A are out of service, and have been since March! This won't affect your journey to Rosa's - except make it quicker! - but it might be helpful to know when you're planning your itinerary).
Very close to Cipro station is Bonci - THE place to go for pizza al taglia and supplì in Rome - not that I knew, I stumbled across it! Take a ticket and get in line - its worth the wait! There is also a Sicilian Pasticceria just before you cross at the traffic lights to get to Rosa's, which I frequented more than once!
Overall a great stay and I would definitely recommend!
