If your station is Warren Street then you might find Euston Square,
Great Portland Street or Regents Park just as convenient to use.

Although Regents Park is currently closed for refurbishment.

Hammersmith for Hammersmith & City Line requires an interchange at
street level but if you're prepared to do that it may be your best
option.

This is the route I take to Great Portland Street from Northfields,
provided the H&C is working. It's certainly at least worth holding as
a backup for if the Bakerloo/Northern are delayed, if either GPS or
Euston Square are convenient.
