Alice house is 20 min walk from the Cathedral of Santa Maria del Fiore or 12 min if you use bus (1.5€ if you but from the ticket office or 2.5€ on the bus). The house is very clean and Alice herself is very friendly and welcoming. The Coop supermarket is just 2 min away by walk and you will have many cafes around. I must add that the walk from Alice house to the city center is very nice and beautiful. I recommend this place.
