This is a fabulous location, on the doorstep of the Pantheon! Much bigger apartment than we were expecting as well - a little dated but still fantastic. My elderly father struggled with the stairs a little (there is a lift bit still a few steps from the lift to the apartment) but my partner and I were ok with this.
Check in greeter (Nicoletta) was very friendly, welcoming and helpful. The airport pick up was well worth it as well.
We'd definitely stay again!
