We really enjoyed our stay at this apartment.
Lovely big, well laid-out and stylish apartment. We thought it had quite a luxury feel.
It is a bit away from the traditional tourist sight-seeing central zone - but, it was easy enough to get in (plentiful buses or Uber (13 euros from apartment to Pantheon)). To be honest we liked the location maybe more than being in the centre (where we have also stayed). It was a nice residential area with enough shops, cafes, restaurants etc. and you felt as though you were 'living like a local' (no tourists that we saw).
However - If you did want to walk from the apartment, 5 mins. would take you to the edge of the lovely Villa Borghese Gardens. One day we walked through the gardens and on to the Spanish Steps/Trevi Fountain and the Pantheon - a beautiful day trip.
Regarding the apartment - very nice terrace for relaxing - covered to rain and not overlooked. Some (not bad) traffic noise on the terrace but quiet inside (inc. for sleeping - with shutters closed).
Great bathroom - very high spec. and shower worked well.
Good natural light in apartment.
Good/modern AC (units in both bedrooms and living room).
Smart TVs with soundbars - great for Spotify listening.
I would love to stay here again and would have no hesitation recommending it to a friend.
