Even better than the pictures suggest. Perfect position, kind of equi-distant from all the major landmarks, as well as the Vatican and right in the heart of Trastevere, surrounded by restaurants and bars that start about 200 metres to the south. Nice simple breakfast ready each morning, nice and quiet street, modern fittings in a lovely old building, great bathroom (warning - the hot water takes a while to come through but it's perfect once it gets hot!) and excellent wifi. Love.
Only issue really was that we didn't stay long enough - 4 days wasn't enough to scratch the surface!
