Nice place in the centre of Florence. The studio is well located and nicely decorated, and the communication with Simone was also good and the wi-fi works well.
I do recommend it. Just be careful in case you are coming with heavy luggage, there are 6 high sets of stairs, Simone (who received me), mentioned that he has a shoulder problem and helped me with the small one only. I asked if they could send someone to help me with the luggage at the check-out, and they said they could send someone for 10EUR. I like staying on Airbnb to avoid the commercial feeling, but as they charge for the cleaning service apart from the fees and everything else is a part, it feels just like any other commercial accommodation.
