We really enjoyed our stay at Lorenzo's place! We stayed for four nights in October 2019 and it was not enough time, we fell in love with the city. Everything we wanted to visit was about a 15-20 minute walk from our home. This was fine for us and we enjoyed being a little out of the hustle and bustle, but still close enough we could walk to everything. The home was clean and provided all the items we needed for our stay. We felt it was in a safe location.
The only thing to note is the home is on third floor. This meant we had to carry our luggage up several flights of stairs to reach our home away from home. This did not hinder our enjoyment of our stay. We would still stay here again upon returning to Florence, but is just something to prepare yourself for upon arrival.
