Addicted to handstands!
Don't want to dishearten you Fozzie but she sounds like one of those twats that just complain coz they're twats. Do stuff if you like but I'd guess she moan anyway. Buy her a pair of earplugs and tell her to deal with it! Go live somewhere in a cave if you can't handle neighbours!
Not sure it's twattish behaviour... Maybe you are both suffering the effects of badly sound proofed living, which is so prevalent
The flat I lived in before was quite horrendous for this, just the sound of normal living seemed to get amplified, and this block of flats I lived in had concrete walls! It's sad that bad building practices can ruin some many neighbourly relationships.Don't hate her, hate whoever converted the house.
Do they have legislation on how to build flats properly? 

My joy when the old cow stopped speaking to us was great. I suspect Fozzie's neighbour is cut from the same cloth! Just presenting a possibility
Looks like I'm stuck with the noise for a while then, since the housing association need to approve of any d.i.y. work and I doubt the neighbours will approve (there's no way they'll bother spending silly money on fixing their flat just because i need peace and quiet, so i can just forget that straight away unfortunately) Looking at some sort of soundproofing panels like we used to have in the music room at school, sort of loose panels you secure from the roof in a wire, but that too costs a bit I'd imagine... For regular walls, I'm putting up bookcases and filling them with my collection of mostly hardback books, so that'll help a bit I think!
