This is our first bad review in our experience with airbnb.
The apartment is definetely well located. However, as a family travelling with small children, our stay at Roberto´s place was a total disaster: not cleaner than other more modest places, not as big as in the photographs, not as beautiful neither, there is a lift but it stops one floor beneath the apartment, insufficient equipment (not even a coffee spoon or a fork in the little kitchen!) and the washing machine was simply not working.
You definitely can not give a shower to small kids in Roberto´s bathrooms, who was not specially helpful with our chekout time. As he owns quite a few apartments in Rome he was too busy just to send us an SMS to confirm our departure time.
