I am a bit shocked by your review, given that we communicated during your stay and you mentioned nothing negative to me, except that there's no wifi, but as you note, my listing says that. We don't want to have a modem beaming its waves through the house when we don't need it ourselves.
I didn't realise that you can see into the neighbours' back yard, but note now that you can if you put your face up to the window and look to the side. Otherwise it is very secluded from neighbours and no-one can see into the room. Of course, if you are staying in a built-up area on a weekend, there is a possibility of noise from neighbours enjoying themselves. We have had no other complaints of this nature, and rarely have experienced noise from neighbours ourselves.
I am very sorry about the other problems you experienced. I can assure you that the sheets are changed and washed and the place thoroughly cleaned between visitors. I honestly can't explain what happened there, with the hair. Thank you for drawing attention to the small maintenance items, though of course you could have just told us, not the world!
I hope you enjoyed your stay in our lovely city,
all the best
