Excellent location to see all of ancient Rome. Can walk to many nearby sites, and transit is very close as well.
The place itself is great, very large, and has a washing machine.
I would not recommend this place to anyone with knee/hip problems as it is a lot of stairs to get to the apartment. 10th floor.
The only thing we felt could have improved the stay was air conditioning that works better. Staying in September when it was 30 Celsius, with the AC on high all day, we would come back to the apartment being 28 degrees still. This was a bit too hot for us to be comfortable.
