You're not going to find a better location in Rome, literally right outside the Trevi Fountain which means you're always just a few minutes walking away from the place and in the middle of everything (without any noise).
There is some room for improvement of weird things (full size mirror in a corner behind the bed and heater) and the mattress was not very great.
Like most Italian bathrooms there is more room reserved for the bidet than the shower that is so small that I kept hitting the faucet with my butt causing my back to be scaulded.
But overall we had an amazing time and would recommend the place to anyone.
