The apartment was beautiful, the location can't be beaten - the window opens to see the side of Pantheon, and Laura is such a gracious and helpful host. I couldn't open the door once - the trick is that you need to pull the door a little bit before turning the key - and I was able to get her help right away. She also helped us book the taxi from and to the airport, which was nice and convenient. She communicated with us early before we checked in, so that was great too.
The apartment was uniquely and beautifully designed. The amenity is quite basic, the bed and the sheet weren't the most comfortable, but it was definitely more than enough for us. Internet was slow, but it's Europe. Also it's a 4 floor walkup with steep stairs, which was fine with us.
