Great apartment in a nice area between Spanish steps and Borghese museum. Pictures don't do justice, it is very modern and nicely decorated. It has all the amenities you can ask for, better than any hotel. We were 4 in the family and the kids loved the separate bedroom with attached bath. Tunnel to metro is very convenient, and several good restaurants close by. Uber to Roma termini was 10 euros.
Only one thing they can improve is the sound proofing of the windows, as street noise can bother some light sleepers. Overall great place and host, will definitely stay here again.
