Professional looking for room Jan-Jun

I'm looking to relocate back to the UK having spent 15 years in Asia (Hong Kong, then Singapore). My family will be coming back after the school year, so I'm looking for a room for 6 months from January to end of June. We're looking to buy a house when they get back, hence looking to minimise on accommodation costs while the rest of the family are still in SG.

I'm relatively well house trained, and will clean up after myself. Happy to share in household chores of course. I'm keen to be social when others are, or keep to myself, whatever suits. I like to keep fit, so will be out at the gym or running. I also enjoy a glass of wine on the odd occasion too!

I'll be working at a financial firm near Liverpool Street, 5 days a week. Also likely to be away some weekends to visit my parents outside of London.
