This place was a good base for us to spend a week in Rome. It is in a great location, quick walk to the Vatican and surrounded by a great number of small bistros and other shops.
It had all the basics we needed so we were able to cook for ourselves for a few evenings. I will say that it is listed as 'luxury' and it is not, but overall it was sufficient. There is a window air-conditioning unit to help cool the place, but it is on the other side of the room from the bed so you could not feel it too well in the very high heat of August.
There is no metro or train station nearby so you will need to make use of taxis, Uber, busses or walking. We found most things we wanted to do or see were within a sensible walking distance, including the Piazza Navona, the Pantheon, Castel Sant'Angelo and the Vatican - even the Colosseum wasn't too far to walk, as well as the Trevi Fountain and Spanish Steps.
