My wife and I stayed at Lorenzo's place for a long weekend in florence. The flat was perfect, very central, short walk to everywhere and opposite the mercato foodhall which is excellent. A unique highlight to the flat was the original 17th (I think) century murals/frescoes on the wall, which only adds to the artistic aura that surrounds you all over the city. Lorenzo is a fantastic host, paying close attention to the small details (including booking a taxi for airport and a nice bottle of wine on entry). The facilities were more than good enough, shower was great, flat was secure and (in our mind) price was very fair.
