Great location! So many places in easy walking distance, and others can be easily reached with buses from stops very close by. Piazza Navona is literally one block away. If you choose an apartment in this area, and are a light sleeper, (as I am) the evening/night time restaurant/bar noise may be an issue, and in that regard Maria's apartment was great. I stayed in Rome in the same area before and had a terrible time sleeping, but Maria's apartment is a good option. You still hear some noise, but you can close the windows and have the A/C on and be perfectly fine.
