We just spent four nights in Elvira's apartment and it was one of our top two AirBnB experiences.
The apartment is clean and spacious and in the heart of old Rome. You step out the front door into a bustling neighborhood with a convenience store immediately across the street and multiple restaurants just steps away. Rome's upscale shops are just a couple of blocks away.
In the front room of the apartment you can enjoy the sounds of vibrant city life on the street below, but the rear bedrooms are nearly silent. With the curtains drawn the sleep was divine.
We walked everywhere-- the Colosseo, Forum, Pantheon, Trevi Fountain, Spanish Steps, and Vatican City (30 minute walk). We rented electric bikes and rode through Villa Borghese Park. Elvira is a perfect host and arranged transportation to and from the airport along with a private tour of the Vatican museums.
Someone mentioned difficulty in operating the washing machine. This is Italy and the controls are understandably in Italian, but you can find a manual in English here: http://download.beko.com/Download.UsageManualsBeko/BR/en_US_Manual_7144241500_en_US20170707-111144-687.pdf
We're headed back to the US now and are sorry to say arrivederci to this amazing city.
