My friends and I really enjoyed our time at this apartment. The rooms were all large and had great high ceilings. Having 3 bathrooms also made life so much easier.
The five floor walk up is a bit daunting but the view is worth it. Sitting on the terrace overlooking the Duomo will be the highlight of your trip.
The neighborhood is fantastic. Great restaurants are just outside the door and the location is perfect to walk to the Duomo and Palazzo Vecchio. Even better a C2 bus line is across the street.
The wifi network isn't very strong so I wouldn't recommend everyone getting online at the same time.
