The location is a short walk uphill from the train station Roma Trastevere, so easily reachable.
Starting from Francescas flat I did a sightseeing tour within a day all on foot. So if you like walking, it is a good base to start for all the major sights in romes city center. Be aware that Ollie the cat likes much attention, cuddles and can get wild when you play with her. So in case you need rest, close the door. The Bed is a convertible sofa that is surprisingly comfy, I slept better than in my last hotel bed.
I can recommend staying here, and if I'd visit rome again I will probably book another stay at Francescas place.
