Hotel/B&B in London

[Sinkingfeeling]

We're hoping to take the 3 dc (8, 8, 6) to London for a weekend towards the end of March or beginning of April. Can anyone recommend somwhere to stay that is reasonably central? We don't need parking. Stuff we'd like to do: Foundling Museum (Bloomsbury), Tower of London/HMS Belfast, Imperial War Museum (not sure if we'll manage to do all of that!)

Thanks

Premier Inn at County Hall. Family rooms, beds are comfy, rooms are clean, location is excellent for weekend with kids.
