Mary And Marina's place is one of the more comfortable places I've stayed in while visiting Florence over the years. One of the unique aspects is that it is right off the street so there is not a lot of stair climbing, and because it is in a quiet neighborhood there are no drawbacks to ground floor access. It is very good if you want something a little out of the main tourist areas but not totally disconnected. Bed was very comfortable, communication very good, well-equipped kitchen. With the heat, I was at first worried at the fact that there were only fans with the excessive heat, but that ended up being more than enough, and in fact a little more comfortable than A/C.
