Giovanni's place is centrally located in the city centre of Florence. It is a lovely, clean and comfortable flat. There is plenty of room for four people who will not mind going up several flights of stairs. The bathroom is clean and functional. It is quiet at night even though it is centrally located.
It is possible to drive there and use your car for your daily tours as long as you don't make the mistake of driving into the city proper. We went to Cinque Terre, Pisa and Sienna.
