i lived in high holborn last year. it and the LSE were so awful, i transferred to another university. high holborn is a very anti-social place, so i recommend you do everything in your power to make friends with the limited number of english-speakers who live there.
never close your door. unless you're asleep or having sex (i mean if bf/gf from back home comes to visit...heaven forbid any real LSE students have sex - they're too busy reading books on the chinese economy in the library all night!).
also prop open the front door to your individual flat. as you will soon see, your security tag opens your flat's front door. how the hell are you supposed to socialise with anyone but the three you share with when they practically ask for a data sample to open any doors? so again, i recommend a policy of propping all doors open, and just closing them when everyone's gone to bed at night.
don't put off arriving. arrive on the first day you are allowed to. i came two days later and making friends was a nightmare.
bang on those flatmates' doors!! even if it's just to be told "i'm busy". two out of my three flatmates were socially inept, solitary geeks who spoke little english. at least i found this out straight away and didn't waste any time on 'em!
the cleaners are schizos. if you leave a YOGHURT POT out in the kitchen, they WILL report you to tim forsyth (the warden) and he WILL send you a strongly-worded letter, in which you are told to get the kitchen spotless or be fined. now, as my flatmates were a bunch of pigs who made that kitchen a health hazard and refused to do ANYTHING about it, i didn't see why i should clean up after them EVERY DAY. so we all got fined. EVERY WEEK. so i recommend drawing up cleaning rotas, or at least agreeing that everyone does their fair share. you will, invariably, have some lazy arse in your flat and you should make it clear to them from the start that you won't be fined for them. it avoids blazing rows later.
you're kinda lucky, in that all LSE halls are non-smoking from this september. because three out of four of us smoked last year, and then one non-smoker was continually writing us all angry notes and complaining to the warden. even when we smoked in our own rooms, not in the kitchen/hall, out of consideration for the non-smoker. so that's one argument avoided. but are the smokers on the eighth floor really going to go and smoke on the pavement, in the snow, at 4am? i think not. so still, reach some agreement with your flatmates right from the start about smoking policy.
the location of high holborn, in relation to uni, is the best thing about it. most people walk along high holborn, until they get to sainsburys (say hello to simon - the lovely big issue vendor from leeds), then turn right down kingsway until they get to uni. but it's far quicker to turn right onto drury lane straight out of high holborn. then take a left onto great queen street. then you're back on kingsway, but almost opposite the LSE.
erm also high holborn is right next to the tottenhem ct rd, and so near oxford circus. which, if you are a shopaholic like me, is heaven. and the shops stay open til like 10pm, habitually. christmas shopping down there was wonderful. most people at high holborn seemed to take forever to realise that if you go out and turn left, in two minutes you are tottenhem ct rd. it's nearer than holborn station. and different tube lines run from there - like the northern line up to camden town. which is handy!
my other favourite thing about that area was winter nights by the thames. when my lectures were over for the day, i always walked down from uni to temple (2 mins) and walked along the river up to westminster. this was mostly out of blatant sentimentalism - my boyfriend and i did it every time he visited me in scumdun - but it was very beautiful. and nice to clear your head after a day of lectures.
and speaking of lectures: there are some gems on the teaching staff at the LSE. catherine hakim (rational choice theory!) teaches. i felt like i was meeting a filmstar when i met her, i think she was a little bemused. prof sarah franklin is also a LOVELY woman. she was my personal tutor, and even when i was desperately unhappy and erm well just slagging off the LSE, she was absolutely wonderful and ALWAYS my advocate. she sorted everything out with my transfer and was just brilliant. prof nikolas rose is also really cool and all the girls see him in his kravatt on the first day and fall in love.
and dr bradley franks is one of the funniest, most inspiring teachers ever. his was the only lecture i was actually listening to, and engaged in. that was my outside module in social psychology. i REALLY recommend it, it's the most interesting thing you'll study!
anyway, sorry, back to high holborn. errm it's in a bit of a **** location (apart from the shopping) because you are just surrounded by businessmen. it's also got a rep as a snobby, unfriendly hall (but then, the LSE has a rep as a snobby, unfriendly uni). roseberry is the best, from what my mates said and what i saw. carr-saunders is also good. you can always swap. high holborn is always full of posters from people begging to swap.
ooh another good thing about high holborn - the camp, foreign guy on the front desk. he made me smile daily. can't remember his name.
errrrm so yes. the surrounding area's crap. but as i said, tottenham ct rd tubes run up to camden - the best night out in scumdun. and the central line goes out to the east end. one of my best friends lives in mile end, and some of my best nights out were there.
