I really enjoyed my stay in Florence. The appartement was beautifully decorated, clean and much more spacious than expected. I loved the fact that the location is central; all the main attractions that I wanted to see were situated at walking distance. Even though it is a busy street I, as other already mentioned, I had no problem sleeping because the bedroom is in the opposite end of the street and there is a door in the corridor, which block most of the noise coming from the street.
I highly recommend the place and would happily stay there again.
