We live on the first and second floors of a Victorian conversion. A couple live in the garden flat below us. All our bedrooms are on the side of the house with the garden.
The couple are very nice, but very loud. Their hours are different from ours - we go to bed at 10pm (we have a baby), whereas they are often up all night and hang out in the garden.
Over the past few months, we've had to politely ask them to be quieter (by text) on multiple occasions, as we could hear them talking loudly or playing music in the garden at 11pm, 12am, 3am (!), etc. Each time they apologise, but then it happens again.
On top of this, they have a wood burner which blows a lot of smoke right into our flat, and they also smoke, which also blows into our flat (particularly the baby's nursery). We have only mentioned the smoke once, and they were apologetic.
We really don't want to fall out with them, but think we need to have a proper chat rather than just text every time. Would we be reasonable to raise this? (If so, any advice on how to do it nicely?) Or is this just part and parcel of living in a flat? I'm aware our baby probably disturbs them too, and they've never complained.
Thank you!
