Arianna and Michele's place was pretty fantastic for what we needed. We wanted something affordable, close to all the sights in Rome (Colosseum, Trevi Fountain, Vatican City, everything else you can think of that is iconic in Rome), and that wasn't sketchy (sorry, just not a hostel kind of girl). Their apartment was all those things. Michele was there to greet us with the keys to our individual room, apartment, and the building so we felt pretty secure leaving our things in the room. I think the other four rooms were occupied by other couples/people but we barely saw them and I don't really think we had to share our bathroom. (There's two bathrooms.)
There's a fully stocked kitchen and a washing machine which was pretty awesome so I didn't have to stress about doing a bunch of laundry when we got home. Overall, it really was what we needed. If you're looking for the glitz and glamour and don't like possibly sharing a bathroom or occasionally seeing someone throw laundry in the washing machine, this place isn't for you. But if you're the type of traveler who is more out of the room than in like us, this place is perfect for you.
