You will not find a better location in Rome. The apartment was comfortable and central to everything. Ilia was quick to respond and communication was effortless. Her husband Fabrizio checked us in immediately upon arrival and explained everything.
We stayed in January and the heat worked very well.
A couple of items to note: (1) The hot plate in the kitchen takes a long time to heat up, so a quicker way to get morning tea or coffee would be to go to Il Barretto, the bar downstairs, which has very reasonably priced coffee and breakfast items. (2) Hand soap is provided for the bathroom sinks but otherwise you will need to bring your own toiletries (which we had done in any case).
