Been trying for weeks. Several weeks ago got Holiday Inn Bloomsbury for three nights later this trip for $125/night, and should have tried to extend stay, but was hoping to get better hotel later on. As it turned out, for several weeks I bid up to $155 for 4* in Bloomsbury, Westminster, The City and Mayfair with no luck. Even tried 3* in the same zones up to $125 with no luck. Finally out of desperation opened up the Kensington zone, although I had been told it is too far out of the way. Started at $110 for 4* and got counter offer of $141. Needless to say, I rejected it, and continued bidding at $5 increments. Got this hotel after adding Bloomsbury, Westminster and the City zones. Hopefully will be okay. TripAdvisor reviews are pretty good for this site. Total $309.64 for two nights after fees.
