Boscombe was a dump, even though some of the B&Bs on Wesby road were OK!
You're better off staying there until you can rent a house. Most people on the course would be willing to share. Check out the board in the main office.
I stayed at a place from that was being advertised on the notice board that was a private house but I was given free reign to the ground floor and all for £70PW.
Jacquie Rhodes knows of the place (if she's still an instructor on the Aerodrome course?) as it's a friend of hers.
Best of luck, hopefully the exams are all multiple choice now instead of the wrist killing 20 pages of MATS 1 transcripts that I had to do!
