We had a very pleasant stay at Lorenzo's place. The apartment's location is perfect and is just a short straight road from the duomo; you can see the duomo from the apartment. It was very convenient for us when we walked around Florence. The apartment is well-furnished and clean; the bed is comfortable.
Lorenzo and his friend Andre were very friendly and helpful. Lorenzo was very responsive when we had queries. On our last night our key got stuck in the apartment door knob when we tried to unlock the door and Andre rushed down from his home to help us (I believe he ran as he came in panting) and we were really grateful for that. Would definitely recommend this to anyone!
