We never actually met Emma - I suppose it was her partner who let us in and showed us around. He was very friendly and helpful.
The apartment is beautiful with a very big, well equipped terrace which makes all the difference in a warm place like Rome ...:-)
The location is more than ideal: everything can be reached on foot: all the major sights, restaurants, bars, shops ..
I certainly recommend Emma's apartment and very much hope to be back there myself before too long.
