Widad is a very kind and comforting host.
We had issues with parking. Finding a parking lot was quite easy, but finding out if you are allowed to park there is a mess: White lot marks = only residents
Blue lot marks = for paying guests (2€/h, 24€ per day)
Unfortunately this was communicated to us wrongly when we explicitly asked before booking.
All in all, I can recommend the host - and now you also know about the parking situation ;) Have fun in Florence!
