You will not regret staying in this lovely apartment. Most importantly the location is just fantastic. That matters more than anything else. I would definitely stay there again.
Laura was very good at keeping in contact in the run up to our visit. She was there to meet us at the apartment and show us around the place. She was friendly, but not intrusive and let us get on with it. She was also helpful in recommending some local restaurants.
The apartment is exactly as pictured and described - all very clean, new, fresh and modern in an incredible historic building surrounded by narrow streets and funky shops. It's walking distance to all of the main tourist attractions.
There is a double sofa bed in the living room and a single bed on the mezzanine floor. The apartment is open plan, so not a lot of privacy. For that reason it's best suited for a couple. The kitchen is equipped with the basics - proper cooking would not be possible, but in Rome why would you do that anyway? It's a lovely place to stay and we were very happy to come home there after a hard day's sightseeing.
The apartment is on a small street and, although very central, could be hard to find if you're new to Rome. I'd suggest taking a taxi from the airport to save the bother of getting lost trying to find it.
