decent hostel/hotel in wimbledon

got an interview next week at st georges and looks like my mates are all busy so trying to find a reasonable hotel for a decent rate-any recommendations?

I’ve never managed to find a decent hotel in the vicinity of St George’s when I’ve been working there.

Best I’ve managed is the Holiday Inn Express opposite Collier’s Wood tube station. It’s within walking distance and the walk takes you past Moose Cycles (nearly bought a Commencal last time I was working there but managed to resist).

wimbledon is very easy to get to from waterloo, i dont know any hotels in either place unfortunatley
