Emanuele gave us great directions to the Airbnb both by metro/bus and taxi.

The Pros:
+Close to the metro to get downtown, the ride is about 10 minutes.
+The room is very large.
+Your own bathroom, though it is across the hall.
+Warm water and didn't seem to go cold.

The Cons:
-There was a problem with the window shutter, got stuck, had to stick my hands up in the contraption to unstick it. Also the balcony was locked so you cant get out to look around in the morning.
-Very loud at night, the walls are super thin. So you can hear the traffic and other people in the hostal. Wasn't a huge deal for us but those who can't sleep because of this just a heads up.
-Internet needs to be reset quite often its more of a wireless hotspot than wifi. But worked well when on. :)
-The room doesnt get cleaned while you are there, and only one towel per stay.

This is more of a fancy hostal than an Airbnb. Donuts, tea, coffee, milk, juice, was left for us in our room. The coffee was pretty quality for instant though (you have hot water in your room). Dont plan on sitting down.

Something to remember its a place to rest your head, when in Rome you are walking all day. This was a perfect place for us to stay. I would recommend it I just thought a fair review was in order.

Cheers!

Have a great time in this lovely city and try an affagato (ice cream and espresso!)
