First advise: Florence is really expensive! Taking this into account, the apartment is good for the price. The location is quite good because you can go by foot or take a bus (it is close to the house). There are many restaurants (better prices than in the center) and in general is a good area. The house is old so you hear the cars from the street. For us, the earplugs are a must on our trips so it wasn't a problem :)
The house is nice, even though we expected it bigger from the pictures. The communication with Irma was good, she helped us with all our requirements.
