We had a really good time at Re di Roma apartment. It is very well communicated with the city center by metro, and even walking wouldn´t take longer than 1 hour. The apartment is placed in a quiet neighborhood, which was great after spending the whole day in the city center. It also gave us a view on how the "real" people from Rome live.
The only issue we had was with the internet connection. It didn´t work properly even though we were only using it for whatsup or checking emails.
Overall I would say it was a pleasant experience
