Firstly, I'm very sorry to hear that you experienced some issues during your stay with us. Please allow me to address your concerns.
In regards to the sheets, I am unsure which stains you are referring to, but it is true that there is some faint discoloration due to frequent washing. Please rest assured, the bedding has been replaced by a completely new set in order to ensure this issue does not occur again in the future.
Our neighbors are usually a very quiet and friendly family, and I would've been more than happy to speak with them on your behalf to ensure that you were not disturbed any further during the remainder of your stay.
Our priority is to be able to offer a very well-maintained and comfortable room for our guests, and I wish you a safe journey home.
