We had a great time in Florence, Frederik was very disposed and waited for our arrival, even when we didn't know for sure the time.
We felt very confident and freedom to use the apartment to our disposition.
They helped us to do changes to accommodate our children in the room.
The apartment is in a great location, just a few steps from Duomo. We were comfortable and happy with our stay in Florence.
Thanks for all Frederik :).
Regards.
