It is no longer Bournemouth Flying Club for commercial training. They set up BCFT - Bournemouth Commercial Flight Training.
If you try searching on that and Stapleford I think you will find positive posts for both. Remember that most people don't try more than one school, so when so many say "...go with X" then they are simply saying that they had a positive experience there, not comparing it with any other. They cannot make your decision, really you should check here for a few people's experience but visit any schools you are considering to get the only proper impression you can.
