Niccoló and his friend Simone were very nice and helpful, even saving us some money. However the apartment had some "turnoffs": the water pressure was very low and made the showers annoyingly slow. However I've lived in Florence for a year and I know that it's very common over there. The bed mattress did loose the planks with almost any movement that we made while sleeping, giving us some scary times, so we had to put them back again. Also in the pictures you can see a portable oven or similar that is no longer in the flat. The door that separates the common entrance with the other flat (it's an old big appartment splitted in two) seems an office door, with big glass windows in it and a curtain. That doesn't give very safe sensations, specially when the other guest, whom you share the principal door with, forget to lock it all the time.
In general, the appartment was ok, but just ok, for the "basics" provided were four towels and the necessary clean blankets. It's the minimum required but with that profits in many other Airbnb you find more stuff like some oil to cook the first day and cleaning products. That being said and knowing those things in advance you still can enjoy the magnificent location of the place, a very wide bed and the cozy kitchen.
