We're training in from Bath and leaving out on the Eurostar. In the meantime, we need a convenient hotel area where, in order to sightsee, we won't be overcome with steps to the Underground(?) Is this a legitimate concern for the elderly? Had originally thought we'd mostly use the bus.
Our most important sights will be the Tower of London and the British Museum. After that, we're open to learning about others' favorites. Thank you!
