Cons: Air condition didn't work in main apartment that included kitchen, living room, 2 bedrooms, and 2 bathrooms. That was very disappointing and those who stayed in that section sweated it out all night, can't handle Rome in Summer with no a/c--and this was in June (supposed to only get hotter). We contacted host, he gave us some trouble shooting tips to restart electrical panel, but didn't work....air condition would just blow out warm humid air and also kept turning off by itself every minute. The wifi also didn't work. Those 2 things are my 3 star rating since I felt like they must have known ahead of time that this section didn't work since the person cleaning house had it on when we got there.
Pros: Close to train station-Roma Termini--we walked with our luggage, about 10 minute walk. The hosts were accommodating with storing our luggage, let us drop off early and leave later next day since no one was checking in--that was a huge plus! They also arranged drivers for a fee to take us to airport in Ciampino. This worked great. The rooms were clean and 12 of us stayed there.
Overall, liked the place and how accommodating hosts were, just needed that A/C to work. :)
