Professional seeking occasional London room

35-year-old professional classical pianist and composer, Oxford graduate, based outside London seeking a quiet, comfortable double room as an occasional London base.

I would typically stay for around a week at a time, perhaps once every month or two, with dates arranged in advance. I am not looking for a permanent tenancy or to move to London.

I'm quiet, tidy and non-smoking, and would particularly suit a homeowner who has a pleasant spare room but doesn't want a full-time lodger. Happy to pay an agreed nightly/weekly rate and provide references.

Ideally central, west or north-west London, although I'm flexible on location for somewhere quiet with good transport connections.
