Monica was a great host! The apartment is a small basement apartment which worked perfectly for the three days we were in Rome. It is a bit of a walk to the centre of Trastevere (20 minutes). There were also buses but we just walked everywhere. Only complaint was that since it is a basement apartment, it can smell a bit at times since the air circulation is poor. However it didn't bother us much. Air conditioning worked great and she even left coffee, water, and some little cakes for us. Would definitely recommend :)
