I arrived after midnight at Marco's house because train is not often and finish early on Saturday but I didn't know. But he was kind and welcome.
And he prepare breakfast for me and he helped me to book the train and gave me many information.
His house is almost museum and looks wonderful! He had been teached about interior so his sense is really great. Location is not bad. Of course it is not walking distance to center but there is busstop in front of his house. It was convenient to move and takes 15mintes to the center. The weather was unexpectable cold but heating is not available. So I slept wearing his shower gown and he allowed.
It was very comfortable to stay and unforgetable memory for me. Highly recommand to travel florence!
