One word to describe the host and the apartment - "fabulous" The apartment is in an excellent location; not too close to the central hub and not too far away that you don't feel the vibe that is Rome. Public transport is plentiful and there is a good scattering of shops and cafes around the corner. The apartment (and complex) was clean and had everything - even a travel adapter, and spacious enough for my family of four with 2 adult children.
Barbara also organised our airport transfers with a private taxi - Paulo; who turned out to be equally brilliant. We had some time to spare so he showed us a few sites off the usual tourist track.
One more thing, the apartment has the fastest internet speeds I have ever seen; which is very handy these days.
Overall a wonderful experience in what is truly an amazing city. Highly recommend this apartment!
