Dr Johnson’s House
Near Fleet Street: a small literary house at £10 standard admission. It involves stairs throughout, so it does not solve an access problem simply by being indoors.

When: Tue–Sat 10am–5pm; Sun noon–4pm. Closed Mon. Check occasional functions.

Put a plan together
Choose the nearest suitable indoor activity that is open and available. If you need to book, do that before travelling. For a brief Covent Garden gap, the Royal Opera House public spaces can be more realistic than a museum across London. For a longer afternoon, give one collection time rather than turning the day into a wet dash between venues.
A few useful answers
Are these all step-free?
No. Indoor and accessible are different attributes. In particular, Dr Johnson’s House has no step-free access. Check each entry’s access note and the official venue guidance.
Why no outdoor audio walk?
This list is for an outing that stays indoors. Cobble walks may suit other plans, but they are not automatically a solution to a rainy-day request.
