I stayed there last week for 4 nights for business.
I got both Breakfast and 250 points as the Platinum member.
I also got upgrade to one bedroom business suite.
The room is nothing special, just spacious.
For room, Grosvenor is far better, but the price is much cheaper at 4p.
Thanks Tak. I'm expecting it to be somewhat more basic than the Grosvenor, but as it's less than half the price for this particular trip, hopefully the value equation helps ease the differential!
