B&B Manchester with parking

I've not used Manchester before but I will be looking for an overnight stay
with around 21 days car parking near the airport. Inclusive deals would be
better especially if they included transportation to/from airport. Most of
the hotels will do a 15 day deal and additional days to be added on but none
as far as I can see do any longer. Has anyone got that well kept secret B&B
they would like to share? What experiences have readers had using the
hotels and additional days?

regards
