This is in a central location for exploring Florence. Unfortunately for us the bedroom had bed bugs, and I received over 40 bites.
We contacted the owner to give him chance to address this but he denied there was a problem, claiming it was mosquito bites. However it was cold when we were in Florence and there were no mosquitoes. Besides the worst of the bites were on the stomach and thighs, and a mosquito would have had had to bite through several layers of clothing, including jeans and a coat. I cannot think where else the bites could have come from.
This problem needs addressing urgently. To be fair, they may have been bought in unwittingly from somewhere else, but it is the host's responsibility now to clean out the flat and destroy the bedding.
