Professional, high quality rental required

I have a fabulous new role and I am looking for somewhere professional, safe and homely to live whereby I can make myself at home in a large en-suite double room, with easy access to a tube line and with a car parking space for my car during the day. I would like a washing line outside to dry my clothes on. I am finding all of this a tall order to ask for! Please contact me if you have something suitable. I am a mature professional who can get on easily with all walks of life. I have rented for 5 years in the same house and now I need to make a move. Look forward to hearing from you!
