My family & I enjoyed our stay at Lorenzo's home! The home is very near SMN Train Station, this was a huge plus because we had to do minimal walking on Italy's (mostly) cobbled streets to get to the home. The home is also within walking distance of tourist hotspots & also near Florence Ice Village so we could enjoy the Ferris Wheel and get a beautiful view of Florence.
The home is beautiful & quiet - exactly like the pictures! You have to go up one flight of stairs to get to the apartment but this was doable for us.
Lorenzo is very communicative - he sent the exact locations of where I can find luggage storage lockers (we arrived much earlier before check-in time and we stored our luggage nearby while we explored Florence before checking in) & also of where we can dispose of our rubbish. He also checked in on us during our stay.
All in all, I would highly recommend staying here while you're in Florence :)
