We have been greeted by a Giovanni employee who showed us the place hotfoot (3 floors).
We have first been given a room smaller than that we booked, with only a small pedestal table, and a balcony communicating with the room of an other customer.
The kitchen advertised was very dirty: stagnant water in the sink, a lot of rubbish under the kitchen worktop, dust everywhere. Obviously, the kitchen had not been cleaned up for several monthes.
We complained to the employee, she replied that they do choose how they allocate the rooms, and that if we were not pleased, we could search an accomodation elsewhere and ask Airbnb for refund.
Facing our insistence, they gave us on the next day the room we booked.
Regarding to the breakfast:
The breakfast is served starting 8 AM to 9 AM (exceptionally from 7:30), not easy to go out on trip early.
Some reviews are wrong: the pastries are not at all home made, but industrial pastries warmed up with microwave, such as the coffee.
