It's not hard to find Raffaella's place from Firenze S.M.N Station by bus C2 even though the address sign on the street is confusing the first.
The place is near Santa Croze Cathedral and other sightseeing spots.
Especially Sant' Ambrogio Market!
When I arrived at the Raffaella's place, her daughter has welcomed me and explained the room and facilities. I didn't use Kitchen but they provided an electric coffee pot and several kinds of tea bags in the room.
The bed was comfortable and kind Raffaella gave me one more blanket because of cold at night, but I would have appreciated if she had turned on the heating system only during sleeping time. The air in the room was chilly. The bathroom is clean and good.
Except cold, I was usually satisfied with 5 days stay in Raffaella's place. I recommend this place :)
