We had a great stay at Giovanni's.
We booked this place because it has a private and secured parking place. This was perfect. The accommodation is in the ZTL so you'll have to pay 10€ to Giovanni and he will pay the pass with the authorities.
I think the accommodation is really perfect for a couple. For 2 couples, the sofa bed is not really comfortable and the living room becomes a bit incommodious. We stayed there in winter, it should be better in summer as one could make use of the terrace to eat and chill.
The apartment has all the equipment you need, and even some shampoo and conditioner. The place is well decorated and feels classy ! The location is super great, about 10min of walk to the Duomo and the city center. (A really good indian restaurant is a few minutes away, in the same street !)
Thank you Giovanni for our great stay, we will come back for sure :)
