The bathroom has a weird system of pumping water into the toilet. It is electric, so whenever you flushed the toilet, there would be a loud rumbling noise while the toiled reloaded. Also, since it has this pump, you cannot throw anything in to toilet. Not too much of a problem, but where I come from, toilets are used to throw away any personal items and toilet paper, that would otherwise look vulgar sitting in a trash bin.
This B&B is excellent. The staff is very nice and informative, the location is a little further than the other hotel I stayed at, but close anyways. But the hotel was amazing. The room was very well decorated, and it was really cozy and comfortable. There is always fruit and cookies that are free in the kitchen, and the water is really just the cost of it, the owner doesn't make profit on selling you water. I stayed in another recognized hostel in Florence and only moved to Leone X because the last night there was no more room in that hostel, but looking back now, I think I'd rather have stayed all the nights here!
