There were two main issues for me of concern.
One related to traffic noise, and noise from the street given that the apartment faced onto the street and had only single glazed windows.
The second issue related to heating issues, given that I arrived in winter in the middle of a cold snap with overnight temperatures around 3C. I did not have a thermometer with me, I do not normally travel with one. If I had I am sure the temp inside at night was below 10C. There was no heating provided and when I asked this was initially refused with some excuse about electricity prices, until I asked again the next day, and suggested via Airbnb App that this was a deal breaker for me. I was well equipped for the cold with thermal underwear, down jacket and a beanie.. However I think most bystanders would say that it is unreasonable to expect a guest to wear these inside an apartment in winter. These issues could be resolved with double glazing of main window.
