This apartment served us well for our 4 night stay in Florence. We had a few troubles upon arriving at the Florence train station, and Annalisa went out of her way to meet us and help us for several hours.
It was spacious for a family of 4. Clean, and comfortable. The high ceilings and arches were beautiful. There is a bit of noise from the street, but the trade off is it is on the ground floor.
I like that it was near a grocery store. It was also not too far from the Accademia Gallerie. Annalisa pointed out to us that the museums were free on the First Sunday of the month, and the best hours to go so the lines are not too bad.
I recommend staying here, so you will have a nice place to stay as well as a friend on Florence!
