I was running out of money and couldn't find a job as a developer in Moscow due to language barriers (also, developers don't get paid very well over there) - I tried to apply for jobs in London from Moscow but recruiters were ignoring my resume (probably because I was in Russia and didn't have a UK phone number). So I decided to fly to London and rent various AirBnBs (changing every week or so) while desperately applying for jobs and attending interviews. Thankfully my risky strategy worked out in the end and I managed to get a decent job and found an apartment in London.
