many thanks for the advice guys!
i agree on the fact that the extractors should be clean, and I would be willing to pay any reasonable charges! It was one of those things missed out on the list, while concentrating to clean the oven and the rest lol... , and with removal my things to the new place.
I will see what's their reply on Monday and see. I will ask for proof for the certains, as the agent keep saying it has professionally clean.. blah blah blah...
to be honest, if he is checking things in a more attention to details / professional manner, and not just standing up and looking for dust at the doors edges, i wouldnt be so fuss about it.
Some agents are really difficult to dealt with, like the the previous apartments I just moved out. I have been renting places in the last 4-5 years, and havent really come across an agent as cheeky / bad as this.
Things should solved eventually, at least i can wash my car easily at my new place
Cheers
