We chose to stay here after friends of ours previously stayed and recommended the apartment to us. We would in turn also highly recommend both the apartment and Andrea as a host.
A lovely apartment, more spacious than the photos suggest! Spotlessly clean and comes with everything you need (kitchen equipment, towels etc). It's in a great location, we walked all over the city from the apartment (furthest being Vatican City). There is a large taxi rank just at the front of the colosseum along with a metro station if you don't fancy walking but if you're up for exploring by feet then it's certainly do-able.
Andrea was very helpful, lots of communication before we arrived. I'm coeliac so thought I would really struggle to eat in Rome but Andrea sent me some links to restaurants (Mama Eat was the best if you're gluten free!).
Andrea also arranged transfers to/from the airport - the only downside is that taxi's sniff out a tourist and up their cost, take an extra €20 ontop of the estimated quote just incase!
We loved our stay in Rome, thanks again Andrea! Ciao :-)
