Carmine is very warm and welcoming! He carried my luggage up the stairs, let me stay a few hours after my check out and accommodated me last minute evening when I arrived in Florence.
The location is central and yes it's above a market but I didn't think it was too loud. I suppose you if you left the window open at all times. It has a full kitchen, washer, tub and shower. The only thing I didn't think of bringing was my own towels. Other than that, great place for the price!!!
I would definitely stay here again when I return.
