If you want to see all the important historic sites in Rome, Maria Teresa's apartment is as close as you can get to having easy access to them, and for a good price too. It's also conveniently located between two metro stations (one on the red line, another on the blue). We loved that there were cafes along the main road just in front of the apartment where we could grab a caffe' and a bite at the start of the day. Maria Teresa was very quick to respond and very proactive in ensuring everything regarding our stay was fine. Highly recommended and many thanks again to Maria Teresa for being an attentive host.
