Room needed in a quiet, homely flat/house

Looking for a room ideally in a 2 or 3 bedroom flat/house which has a quiet, relaxing atmosphere.

I work full-time as an orchestra manager in south London, often at weekends and evenings - though some weeks are standard Monday to Friday in the office. Ideally looking for housemates who are independent but can also have the occasional relaxing night in (and wouldn't mind sharing a house with a classical musician who keeps unusual hours some weeks!).

Not a party-goer, so prefer to share with more homely types! I'm well house-trained and like to keep things clean and tidy - especially in the kitchen.
