Dh has a flat that he's let as we moved area so we're now renting elsewhere. it is let to a couple with a 5yo ds, they are very nice and great tenants, they've been there two years.
A year ago new tenants moved in downstairs from our tenants and since then have made multiple complaints both to our tenants and to us as landlords. They complain the 5 yo ds makes noise running round the flat above them, spoiling their dinner, that he has tantrums and makes their walls shake (wtf???) and runs in to his mum and dad's bedroom at. between 8 and 9am at weekends, meaning they can't sleep in late.
The flat is fully carpeted, our tenants are decent people and have tried to minimise noise but these downstairs neighbours are still complaining. Aibu to think the complaints are unreasonable and if you want silence a flat isn't always a great option? I've lived next to children/babies in the past and accept a certain amount of noise is inevitable, it's hardly like a parent would encourage tantrums...I feel sorry for the poor family, I know they wouldn't want complaints, no one else has complained about them previously.
