Regarding the extra cost for washing up items we never charge for leaving a few extra cups, but please note we had guests in the past who left a huge pile of dishes, mugs cups, pans etc, it really is not acceptable as there is a dishwasher in the flat.
There are trundle beds in the apartment( two single beds that can be put together to make a double), the photos are self explanatory.
We never had any comments regarding the noise of the water in the building, please check our other reviews.
Please note there is a sofa bed that can be used to sleep on, if 3 guests staying, but if it is only one person or couple no bed linen is provided for the sofa bed.
We do not believe the bed cover was not clean, as all bed linen and towels are replaced with fresh after guests check out and before new guests move in. Strange that you never reported that to us on your arrival or during your stay.
Under the booking terms and conditions it says:
Our policy is that we can only deal with a complaint or special request if it is
made immediately during the clients stay, in order that we may investigate any issue and have the opportunity of putting it right if it is a genuine grievance. Any complaints made at the end of the clients stay or after departure cannot be dealt with.
Your last sentence contradicts the feedback from other guests.
