Carmine is a very nice and welcoming person. We saw him once because we arrived late and we where always moving around firenze.
We were moving all over Florence because the central location of the apartment allowed us to go everywhere and come back to the apartment for a brief rest and go the toilet.
The toilet is very new and very clean.
The only problem could some people face is local market. For me I did enjoy it! Being within the heart of a lively place added to my experience. Seeing the market starting I the morning and ending by sunset is something I enjoyed. Even if I am a light sleeper; but I do wake up early to start my tour.
Just one day after our arrival; carmine contacted us and asked us if we need anything and that he wants to see us. And he was at our disposable all the time by phone call or sms.
Thanks carmine :)
