My interactions with Maura before our trip were very good, and the flat was great. It is a bit too far from the centre in my opinion, but if you're after peace and quiet then it's ideal. And it has several nice restaurants near by.
Beware of the €60 cleaning charge that you're supposed to pay on arrival. I think Maura should include that in the price per night rather than hidden in the apartment rules (where I didn't look). Also, note that the flat is on the 4th floor with no lift. If you have kids and lots of luggage it might not be the best.
Louisa was the lady that met us at the flat and she was lovely!
Florence is a very busy town and it was packed with tourists, but overall well worth a visit!
