I also live in Bletchingdon (about 5 minutes drive from the airport). I work in Kidlington so can provide transport if anyone needs it.
I can't offer B&B accomodation with own TV and en-suite etc, but I can offer the spare room as I would to a friend - with breakfast and evening meals, a roaring fire, cosy living room, internet access (four days without ppruning???), and a set of BGS notes!
To anyone coming to Oxford for exams or brush-ups, send me a PM for more info.
