The staff desk at St. David's Hotels
I made reservations far enough ahead to obtain a ground-level room with full bath (I'm not one for sharing the bath). Initially, the room seemed cramped, but after my first night and day in London it never bothered me again. I wasn't there to spend time in the room! The staff got used to me leaving in the morning and coming back late in the evening, as I tried to fill my days full of London sites.
