I am a retired male teacher aged 66. I am single and a non-smoker.

I am looking for a one bedroom/studio flat. I am not looking for a shared situation. Ideally I am looking in Beds, Bucks and Herts areas.
Although retired ,I am still kept busy by offering private tuition in Maths. For this reason, I would need to be close to transport links as I would wish to travel into London at least two days/week for the remainder of this academic year. Also I am looking for somewhere that is quiet. I no longer drive so have no use for a parking space.

I come from an Irish background. (Both parents).
