Carla was a very friendly and charming host and took perfect care of us.
The apartment was small, but very nicely decorated, clean and tidy. The only remark to make is, that the gallery upstairs, where the bed is, has a very low ceiling that does not allow for one to stand upright, unless you are not taller than 160cm.
If one is unfamiliar with Italy's tourism tax rules, it is worthwhile considering that there is a small tax per person per night. We were slightly surprised by this, but no big issue.
