The balcony is absolutely amazing, even in January. The location is great, a very short walk from Trastevere Station with plenty of taxis or buses to take you anywhere in the city or enjoy the scenic hour-ish walk back. Great restaurants around the neighborhood, some of the best food we've had in Italy and far enough away from tourist traps. The location is a bit loud, so if you're a light sleeper bring some ear plugs. There were some breakfast treats out for us, tea, and cold water in the fridge, very thoughtful. Some dishes I first pulled out were dirty and the bottom of the kettle was caked with lime, which wasn't the best and we pulled out an extra comforter from the closet for the bed and it was covered in stains and hair, so those were the only two "issues", but everything else was spotless. The bathroom feels like a luxury hotel and I loved getting ready in there, although some light bulbs do need replacing. Overall the location and balcony would definitely bring us back!
