For a reasonably priced hotel in central London, I thought the Crestfield was excellent - one of the better ones I've tried. The room I was in was pretty big, the bathroom though small was fine (I've been in much much smaller!), it was comfortable, felt clean, so all good. Only issues really were the noise from the road (though I don't imagine the hotel will invest in triple glazing any time soon) - whoever delivered towels / laundry at 4am was incredibly noisy, a lot of banging, talking loudly on the phone right outsied the window. But I guess not really the hotel's fault.
