Our stay at Lorenzo’s was really disappointing. As other people have pointed out, the bedroom is the first room as you open the front door. It was so noisy from people walking past, cars, motorbikes, etc. that for our first two nights we hardly slept (the third was remotely better, plus I also bought myself some earplugs to get me through). If you are a light sleeper, or easily disturbed by noise, I do not recommend this place. Additionally, the wifi dropped out and did not work for over a third of our stay. As we are not from Europe and traveling without international sims, we are heavily reliant on wifi. It rendered us unable to contact anyone or research our stay in Florence. Lorenzo and Souhayla did contact the internet provider, and it eventually came back.
The apartment is also further away than the map and given Airbnb address suggest - the place you stay is the address given as the meeting point. This is about 2 blocks further away. Having said that, the location is still convenient and only a 15 minute walk to the duomo.
It’s not all bad - the kitchen and bathroom were quite well equipped and clean.
