Cristina was a really friendly lady. Gave us the Rome map and told us about nearest supermarket just across the road from her place. The room was quite big as we got the master bedroom, it can fit 3 person.
However, the address shown on airbnb is not the same as she provided when we arrived in rome.
Wifi was slow (3-4 mbps) and keep disconnecting from our room, probably because of the room distance from router outside.
There's no aircond, only a fan but thankfully it didn't get so hot at night.
Her place was also very full with stuffs and quite hard to move around.
Also, you need to wear slippers in the house as the floor was really dirty as they don't take off shoes in the house.
Her place is 5 minutes walk to San Giovanni train station, but the bus station is just across the street from her place.
