Drinking Tuscan wine and eating local cheeses and meats by the bedroom window overlooking the Arno River and Florence is very hard to beat for this value of money. When you see all those people crowding on the Ponte Vecchio, it's quite fun to think you don't need to. When you see those photos of the bridge, you can always remember those few nights you lived on the bridge!
The place itself has simple (but sufficient) amenities in the kitchen and bathroom, but the company that runs the accommodation operates up stairs and their staff are always at hand to assist with any additional needs (like more pillows!)
