I liked our stay, the cat is very friendly, location is also good - but I wouldn't recommend to go there by foot, take the bus from central station (you can buy the single ticket directly in the bus).
I would also recommend San Jacopino Restaurant, it's very close and you can get really delicious dishes for relatively low price.
Furthermore there is Supermarket Esselunga S.P.A, check it to buy some meal for the breakfast.
I would definately recommend this place in Florence, I believe it is the best offer if you are searching the room with 2 separate beds.
