We are staying in a holiday flat, which has laminate floors (I can see why, easy to clean, but not good for noise!)
We have told the kids to be quiet when walking about, and although they are not perfect, have actually been quite sensible! for a change
We were out most of the day yesterday and today. And have been sat quietly playing top trumps since we have been back.
The neighbour downstairs just knocked and asked (nicely) to ask us to be quiet as they can here us being noisy, and this is their home, but they don't want to spoil our holiday
luckily OH answered the door not me (I would have been polite and apologised, but glad I didn't have to!)
I know kids can be noisy and it is very annoying, but I really have asked them to be very quiet and respectful of neighbours.
It's pissed me off and I am worried about even walking about now :(
I know I am probably being unreasonable, and you lot will tell me straight 
Puts me off renting a private holiday flat, will stick to caravans and cottages in future, I wouldn't come back here to this flat which is a shame as it's lovely.
Anyway whinge over!
