The house next door to us is divided into two flats, both managed by a housing association.
The downstairs tenants are no problem. The upstairs flat has just been vacated by horrendous tenants. We never complained and gritted our teeth. Fortunately, they moved recently. We have now got equally awful new residents upstairs. Won't go into details.
If problems get worse, will the housing association listen to our worries or is it a waste of time?
