Excellent location for those wanting to visit tourist sites or just want to stay in a good area of Rome. Just one block from the Metro line A and Uber is also available in Rome which I used with no issues. There are plenty of restaurants and stores nearby. If you just need beverages there are smaller stores in the same block and the grocery store is just down the street.
The apartment was very clean and had everything I needed for my stay. There are three AC units one for each main room. And as others have stated the apartment is very quiet and the neighbors I met during my week there were also very helpful. The only thing I was missing in the kitchen was a microwave to warm some items, but I was able to use the over in place of one. The elevator was very helpful when I checked in and when I returned to the apartment with shopping bags full.
The other thing I would note is the wifi worked well for checking on trains, buying tickets or checking my email. But it was slower if you attempt to load anything to your iTunes or tablet to watch later.
I would definitely recommend Daniela's apartment for anyone visiting Rome. Daniela was always quick to respond to any questions I had and she was there waiting for me when I arrived and took extra time to show me where everything was in the apartment and how to find my way around Rome.
