We stayed there 4 people... Great location! Almost in front of Vatican..! Maria Cristina is really kind and helpfull! She was wsiting for us at home and she was really kind and cool about our cheking out (but it wasn't supposed to visit the apt other people)! The neighbourhood is really quite and everything in the apt is really comfortable and as it is described! Hairdryer, towels, sheets, fridge, wifi, hot water... everything!! We were totally pleased!! But... after carbonara... 2nd floor is a little bit taugh!!! :-P
We suggest not to take any bus or taxi, because everything is quite near! Even though colosseum (which is the longest distance), is accessible on foot!! It wiil take you no more than half an hour....
