Active 77 year old Male seeks an ensuite room

I am a male aged 77. I am looking for an ensuite double room or self contained studio/flat in the Bournemouth/ Poole areas. I am available to move within a month and have a budget of up to £900pcm. I am happy to share with males or females of any age. Although retired from running my own business I have had part time work since I was 69 -chiefly as an exam invigilator in a secondary school. With mock exams and national exams, this can be very busy at certain times of the year.. I hold a current DBS certificate. I do have 3 pensions and rental income from a property in Derbyshire, so reckon that I'm pretty solvent! I own a motorhome that is stored at a farm and try and get away to explore this country and abroad when I get a chance.
