We had a very unpleasant experience with Lorenzo's. The hosts are not very accommodating and their way of communicating is quite arrogant
We booked the place for 4 nights for 755 euro. Arrived at the property around 10 pm first night. The place did not have hot water, heating and internet. Had to exchange several messages with the host in order to figure out how to fix all the problems - no water pressure in the boiler, faulty wifi router (after five hours of driving with kids I would had rather go to sleep than fixing all the problems).
The place was full of mosquitoes that together with hard and uncomfortable pillows kept all four of us awake a good part of the night. We woke up with a lot of mosquitoes bites.
In the morning we asked the hosts if they have some softer extra pillows and a solution for mosquitoes. We were informed that these requests are not included in the amenities. Moreover, we were suggested to leave if we did not like the apartment and to look for what is required "in higher level structures". The host offered to refund what we had paid.
Facing this arrogance, we decided to leave after the first night. We found a much nicer place for a better price next to the Florence cathedral with extra soft pillows and mosquito repelent machine.
