This place is S.marco square 20 meters from Michelangelo's David.
Hardly a 3min walk to duomo.
If you are staying here, you will be stress free in Florence.
All the major sites are close enough for you to walk around without having to worry about returning back to room.
Clean house. Very safe. Night life is awesome around Duomo, so you can stay out late night.
This was our best city in Italy and best of all the stays.
