Carlotta's home is the best a person who's traveling could ask for, with a couple of small issues that I'm going to point out.
First off, great location for the value, the home is also very big which is a plus after staying in very cramped places.
You have all you need close the house for things like food and other amenities.
Very short walk to the main city attractions.
The person who checked us in is a very nice lady who made us feel very comfortable, we tried texting Carlotta but she didn't answer, when we got there we found out that she was in contact with the lady that would let us in the building and the house. She also spoke portuguese so that was totally awesome for us!
The street is also very noisy so keep that in mind.
In short, we highly recommend staying here if you're visiting Florance :).
