We had a great stay at this apartment. We didn't take any public transport while we were there since everything was walking distance for us. However, right outside the door are the bus stops and a taxi stand, so no issue there. Restaurants are plentiful and many choices available from street food to restaurants (and coffee shops).
The unit itself was perfect for our group of 6 adults and we didn't have any issues. The team at Mamo was great at communicating and was prompt to respond. The air conditioner worked great and was so necessary during out stay - a lifesaver!
Others have mentioned the music outside, during our stay there was music every night and we enjoyed it. It would go on until maybe 11 or midnight. Great view from the windows! But if you close the shutters you couldn't hear it in the back bedrooms. If someone is in the sofa-bed they might hear it but my son and daughter weren't bothered by it.
We really loved Firenze and this apartment was less than a mile to just about everything. Great place to stay.
