Couple (35) seeking apartment in London

Me and my husband are looking for a long term rent. Our last rent was our house for the last 9 years. We decided to move, to have our own space as we are living in a sharing house at the moment. We are working people, full time, 5 days a week and weekends sometimes. Working in central London. We are looking for a decent price aswell and a space to keep our motorbike safe. We don't have kids, pets and we are not smoking. No parties people and no drinking alcohol. We like to travel and usually we are riding out of London in the days off. Thank you.
