Even though I was welcomed by the host while he was still cleaning the apartment in the late evening, our two day stay has been great until we had to checkout. At first the host promised us some flexibility about leaving the flat at least half an hour later. In reality, he acted in a very strict and disrespectful way at 11 am sharp (checkout time). He also started bothering fiercely about the smell of smoke inside the flat which actually came from the clothes we wore in clubs as none of us smoked. Trying to explain this was impossible because of the host's rude attitude. I understand being professional and follow thoroughly guidelines, completely agree; however guests should be respected too leaving them at least the benefit of doubt. It is a pity we have been so unlucky; without this final "exploit" it would have been a perfect great stay.
